  • passing values to pages

    - by Indranil Mutsuddy
    Hello friends, What i am trying here is to pass values to other pages. When i include the following code private void Button1_Click(object sender, System.EventArgs e) { // Value sent using HttpResponse Response.Redirect("WebForm5.aspx?Name="+txtName.Text); } if (Request.QueryString["Name"]!= null) Response.write( Request.QueryString["Name"]); everything works fine the name gets displayed. Now if use MemberId instead, though i can see the Id in the Url, but while checking for Null in other page, its true. Whats wrong?? Now I tried the same thing using session i.e. Session["MemberId"] = this.TxtEnterMemberId.Text; if (MemberSex.Equals("M")) Response.Redirect("PatientDetailsMale.aspx",false ); Page_load event of the other page if (Session["MemberId"] != null) mid = Session["MemberId"].ToString(); IT Works..Could u guys explain the behaviour please? P.S. Can anyone give a breif in layman words about SessionId and its usage. Thanking you, Indranil

  • How to reliably categorize HTTP sessions in proxy to corresponding browser' windows/tabs user is viewing?

    - by Jehonathan
    I was using the Fiddler core .Net library as a local proxy to record the user activity in web. However I ended up with a problem which seems dirty to solve. I have a web browser say Google Chrome, and the user opened like 10 different tabs each with different web URLs. The problem is that the proxy records all the HTTP session initiated by each pages separately, causing me to figure out using my intelligence the tab which the corresponding HTTP session belonged to. I understand that this is because of the stateless nature of HTTP protocol. However I am just wondering is there an easy way to do this? I ended up with below c# code for that in Fiddler. Still its not a reliable solution due to the heuristics. This is a modification of the sample project bundled with Fiddler core for .NET 4. Basically what it does is filtering HTTP sessions initiated in last few seconds to find the first request or switching to another page made by the same tab in browser. It almost works, but not seems to be a universal solution. Fiddler.FiddlerApplication.AfterSessionComplete += delegate(Fiddler.Session oS) { //exclude other HTTP methods if (oS.oRequest.headers.HTTPMethod == "GET" || oS.oRequest.headers.HTTPMethod == "POST") //exclude other HTTP Status codes if (oS.oResponse.headers.HTTPResponseStatus == "200 OK" || oS.oResponse.headers.HTTPResponseStatus == "304 Not Modified") { //exclude other MIME responses (allow only text/html) var accept = oS.oRequest.headers.FindAll("Accept"); if (accept != null) { if(accept.Count>0) if (accept[0].Value.Contains("text/html")) { //exclude AJAX if (!oS.oRequest.headers.Exists("X-Requested-With")) { //find the referer for this request var referer = oS.oRequest.headers.FindAll("Referer"); //if no referer then assume this as a new request and display the same if(referer!=null) { //if no referer then assume this as a new request and display the same if (referer.Count > 0) { //lock the sessions Monitor.Enter(oAllSessions); //filter further using the response if (oS.oResponse.MIMEType == string.Empty || oS.oResponse.MIMEType == "text/html") //get all previous sessions with the same process ID this session request if(oAllSessions.FindAll(a=>a.LocalProcessID == oS.LocalProcessID) //get all previous sessions within last second (assuming the new tab opened initiated multiple sessions other than parent) .FindAll(z => (z.Timers.ClientBeginRequest > oS.Timers.ClientBeginRequest.AddSeconds(-1))) //get all previous sessions that belongs to the same port of the current session .FindAll(b=>b.port == oS.port ).FindAll(c=>c.clientIP ==oS.clientIP) //get all previus sessions with the same referrer URL of the current session .FindAll(y => referer[0].Value.Equals(y.fullUrl)) //get all previous sessions with the same host name of the current session .FindAll(m=>m.hostname==oS.hostname).Count==0 ) //if count ==0 that means this is the parent request Console.WriteLine(oS.fullUrl); //unlock sessions Monitor.Exit(oAllSessions); } else Console.WriteLine(oS.fullUrl); } else Console.WriteLine(oS.fullUrl); Console.WriteLine(); } } } } };

  • Autofac: Reference from a SingleInstance'd type to a HttpRequestScoped

    - by Michael Wagner
    I've got an application where a shared object needs a reference to a per-request object. Shared: Engine | Per Req: IExtensions() | Request If i try to inject the IExtensions directly into the constructor of Engine, even as Lazy(Of IExtension), I get a "No scope matching [Request] is visible from the scope in which the instance was requested." exception when it tries to instantiate each IExtension. How can I create a HttpRequestScoped instance and then inject it into a shared instance? Would it be considered good practice to set it in the Request's factory (and therefore inject Engine into RequestFactory)?

  • How to make pytest display a custom string representation for fixture parameters?

    - by Björn Pollex
    When using builtin types as fixture parameters, pytest prints out the value of the parameters in the test report. For example: @fixture(params=['hello', 'world'] def data(request): return request.param def test_something(data): pass Running this with py.test --verbose will print something like: test_example.py:7: test_something[hello] PASSED test_example.py:7: test_something[world] PASSED Note that the value of the parameter is printed in square brackets after the test name. Now, when using an object of a user-defined class as parameter, like so: class Param(object): def __init__(self, text): self.text = text @fixture(params=[Param('hello'), Param('world')] def data(request): return request.param def test_something(data): pass pytest will simply enumerate the number of values (p0, p1, etc.): test_example.py:7: test_something[p0] PASSED test_example.py:7: test_something[p1] PASSED This behavior does not change even when the user-defined class provides custom __str__ and __repr__ implementations. Is there any way to make pytest display something more useful than just p0 here? I am using pytest 2.5.2 on Python 2.7.6 on Windows 7.

  • Problem in getting response from server in jquery

    - by Alvin
    Hello, I'm using $.ajax(options) method to pass the request to server based on username and password, but whenever I try to print the response by XMLHttpRequest object when response gets successful, I'm getting an empty value. $(document).ready(function(){ $("#form").submit(function(){ $.ajax({url:"Chat.jsp",type:"POST",data:$("#form").serialize(),success:function(request) { alert(request.responseText); //This is displaying nothing },error:function(){document.write("YOU can't");}}); }); }); This is what I'm doing in my servlets code after executing query: try { String user = request.getParameter("j_username"); String password = request.getParameter("j_password"); if(user != null && password != null) { String query = "Select * from users where user_name="+"\'"+user+"\'"+"&& user_pass="+"\""+password+"\""; DBCheck db= new DBCheck(); boolean b = db.doExecuteQuery(con.createStatement(),query); response.setHeader("Cache-Control", "no-cache"); if(b) { response.getWriter().println("Username already exits"); } else { response.getWriter().println("Username doesn't exit"); } } } catch(SQLException ex) { ex.printStackTrace(); } } May I know the problem, and how can I fix it?

  • Django: Determining if a user has voted or not

    - by TheLizardKing
    I have a long list of links that I spit out using the below code, total votes, submitted by, the usual stuff but I am not 100% on how to determine if the currently logged in user has voted on a link or not. I know how to do this from within my view but do I need to alter my below view code or can I make use of the way templates work to determine it? I have read http://stackoverflow.com/questions/1528583/django-vote-up-down-method but I don't quite understand what's going on ( and don't need any ofjavascriptery). Models (snippet): class Link(models.Model): category = models.ForeignKey(Category, blank=False, default=1) user = models.ForeignKey(User) created = models.DateTimeField(auto_now_add=True) modified = models.DateTimeField(auto_now=True) url = models.URLField(max_length=1024, unique=True, verify_exists=True) name = models.CharField(max_length=512) def __unicode__(self): return u'%s (%s)' % (self.name, self.url) class Vote(models.Model): link = models.ForeignKey(Link) user = models.ForeignKey(User) created = models.DateTimeField(auto_now_add=True) def __unicode__(self): return u'%s vote for %s' % (self.user, self.link) Views (snippet): def hot(request): links = Link.objects.select_related().annotate(votes=Count('vote')).order_by('-created') for link in links: delta_in_hours = (int(datetime.now().strftime("%s")) - int(link.created.strftime("%s"))) / 3600 link.popularity = ((link.votes - 1) / (delta_in_hours + 2)**1.5) if request.user.is_authenticated(): try: link.voted = Vote.objects.get(link=link, user=request.user) except Vote.DoesNotExist: link.voted = None links = sorted(links, key=lambda x: x.popularity, reverse=True) links = paginate(request, links, 15) return direct_to_template( request, template = 'links/link_list.html', extra_context = { 'links': links, }) The above view actually accomplishes what I need but in what I believe to be a horribly inefficient way. This causes the dreaded n+1 queries, as it stands that's 33 queries for a page containing just 29 links while originally I got away with just 4 queries. I would really prefer to do this using Django's ORM or at least .extra(). Any advice?

  • Server.Execute - render .ASP from MVC controller action

    - by David Lively
    I need to render an ASP page to a string from an MVC controller action. I can use Server.Execute() to render a .aspx page, but not a .asp page. Here's what I'm using: public ActionResult Index() { Server.Execute("/default.asp"); return new EmptyResult(); } which returns `No http handler was found for request type 'GET'` Any suggestions? I can do something similar with with a web request, but I'd rather avoid the overhead of a loopback request.

  • Java: JSP halt execution on rest of page

    - by bguiz
    Hi, How do you stop a JSP from executing? I have JSPs which kick the user off a page by means of a "forward". public boolean kickIfNotLoggedIn( HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { //code to check if user is logged in req.getRequestDispatcher( ACCESS_DENIED_PAGE).forward(request, response); } In my JSP, I have this code, BEFORE any HTML output: <% //loginHelper.kickIfNotLoggedIn(request, response); if (!loginHelper.kickIfNotLoggedIn(request, response)) { return; } %> If I don't use the return statement, the JSP continues processing, and I get a NullPointerException. If I use the return statement (as is commonly suggested on various sources on the net), I get an IllegalStateException: StandardWrapperValve[jsp]: PWC1406: Servlet.service() for servlet jsp threw exception java.lang.IllegalStateException: PWC3991: getOutputStream() has already been called for this response at org.apache.coyote.tomcat5.CoyoteResponse.getWriter(CoyoteResponse.java:717) at org.apache.coyote.tomcat5.CoyoteResponseFacade.getWriter(CoyoteResponseFacade.java:226) at org.apache.jasper.runtime.JspWriterImpl.initOut(JspWriterImpl.java:187) Any ideas how to fix this, or another way to achieve an access denied page?

  • How do I build a specialized JQuery Timer

    - by Sayem Ahmed
    I have an asp.net page where two grid views are available showing current stock market price updates. I need to update these two grid views every 20 seconds. So I was thinking of using JQuery to do this job. What I need is a timer which will fire every 20 seconds, send an ajax request to the servers, bring the order lists from the server using json and then update those two grid views. If a request to the server is still being served 20 seconds after it is fired, then I want the old one to be aborted without causing any trouble. I already know how to bring objects using json. I just need to figure out how to send a request every 20 seconds and cancel a request if it is still being server for 20 seconds.

  • Sinatra: How do I provide access to a login form while preventing access to the rest of my Sinatra a

    - by Brandon Toone
    I recently created a Sinatra app with a login form (no basic auth). To prevent access to the app unless the user logged in I put a before block in place before do unless request.path_info == '/login' authenticated? end end I quickly realized that this prevented me from accessing resources in the public directory like my style sheet and logo unless authenticated first as well. To get around that I changed my filter to the following: before do unless request.path_info == '/login' || request.path_info == "/stylesheets/master.css" || request.path_info == "/images/logo.png" authenticated? end end If there were lots of resources I needed to provide exceptions to this way of making them would quickly become overwhelming. What is a better way to code this so I can make exceptions for the public directory or even its specific sub-directories and files like /stylesheets, /images, /images/bg.png but not /secret or /secret/eyes-only.pdf? Or ... Is there a completely different best-practice to handle this situation of locking down everything except the stuff related to logging in (handlers, views, resources)?

  • how use ASP.NET_SessionId cookies to check timeout for 2 different web applications

    - by user553858
    Hi All I am developing 2 web applications based on "ASP.NET_SessionId" cookies to check session timeout and also to logout : protected void Session_Start(object sender, EventArgs e) { if (Context.Session != null) { //check the IsNewSession value, this will tell us if the session has been reset if (Session.IsNewSession) { string cookie = Request.Headers["Cookie"]; // Code that runs when a new session is started if ((null != cookie) && (cookie.IndexOf("ASP.NET_SessionId") >= 0)) { if (Request.QueryString["timeout"] == null || !Request.QueryString["timeout"].ToString().Equals("yes")) Session.Abandon(); Session.Clear(); Response.Redirect("Login.aspx?timeout=yes"); } } } } This works fine for my first application. When implementing the same logic for the 2nd application when I press logout in one application, the second application is redirected to the login page. How can I fix this? Best regards

  • Symfony2 Forms: is it possible to bind a form in an "unconventional way"?

    - by DonCallisto
    Imagine this scenario: in our company there is an employee that "play" around graphic,css,html and so on. Our new project will born under symfony2 so we're trying some silly - but "real" - stuff (like authentication from db, submit data from a form and persist it to db and so on..) The problem As far i know, learnt from symfony2 "book" that i found on the site (you can find it here), there is an "automated" way for creating and rendering forms: 1) Build the form up into a controller in this way $form = $this->createFormBuilder($task) ->add('task','text'), ->add('dueDate','date'), ->getForm(); return $this->render('pathToBundle:Controller:templateTwig', array('form'=>$form->createview()); 2) Into templateTwig render the template {{ form_widget(form) }} // or single rows method 3) Into a controller (the same that have a route where you can submit data), take back submitted information if($rquest->getMethod()=='POST'){ $form->bindRequest($request); /* and so on */ } Return to scenario Our graphic employee don't want to access controllers, write php and other stuff like those. So he'll write a twig template with a "unconventional" (from symfony2 point of view, but conventional from HTML point of view) method: /* into twig template */ <form action="{{ path('SestanteUserBundle_homepage') }}" method="post" name="userForm"> <div> USERNAME: <input type="text" name="user_name" value="{{ user.username}}"/> </div> <div> EMAIL: <input type="text" name="user_mail" value="{{ user.email }}"/> </div> <input type="hidden" name="user_id" value="{{ id }}" /> <input type="submit" value="modifica i dati"> </form> Now, if into the controller that handle the submission of data we do something like that public function indexAction(Request $request) { if($request->getMethod() == 'POST'){ // sono arrivato per via di un submit, quindi devo modificare i dati prima di farli vedere a video $defaultData = array('message'=>'ho visto questa cosa in esempio, ma non capisco se posso farne a meno'); $form = $this->createFormBuilder($defaultData) ->add('user_name','text') ->add('user_mail','email') ->add('user_id','integer') ->getForm(); $form->bindRequest($request); //bindo la form ad una request $data = $form->getData(); //mi aspetto un'array chiave=>valore /* .... */ We expected that $data will contain an array with key,value from the submitted form. We found that it isn't true. After googling for a while and try with other "bad" ideas, we're frozen into that. So, if you have a "graphic office" that can't handle directly php code, how can we interface from form(s) to controller(s) ? UPDATE It seems that Symfony2 use a different convention for form's field name and lookup once you've submitted that. In particular, if my form's name is addUser and a field is named userName, the field's name will be AddUser[username] so maybe it have a "dynamic" lookup method that will extract form's name, field's name, concat them and lookup for values. Is it possible?

  • Why is alert not run even though $.getJSON runs fine? (Callback not executed, even though the reques

    - by Emre Sevinç
    I have a snippet of code such as: $.getJSON("http://mysite.org/polls/saveLanguageTest?url=" + escape(window.location.href) + "&callback=?", function (data) { var serverResponse = data.result; console.log(serverResponse); alert(serverResponse); }); It works fine in the sense that it makes a cross-domain request to my server and the server saves the data as I expect. Unfortunately, even though the server saves data and sends back a response I just can't get any alert or the console.log run. Why may be that? The server side code is (if that is relevant): def saveLanguageTest(request): callback = request.GET.get('callback', '') person = Person(firstName = 'Anonymous', ipAddress = request.META['REMOTE_ADDR']) person.save() webPage = WebPage(url = request.GET.get('url')) webPage.save() langTest = LanguageTest(type = 'prepositionTest') langTest.person = person langTest.webPage = webPage langTest.save() req ['result'] = 'Your test is saved.' response = json.dumps(req) response = callback + '(' + response + ');' return HttpResponse(response, mimetype = "application/json") What am I missing? (I tried the same code both within my web pages and inside the Firebug and I always have the problem stated above.)

The reason for integrating this filter comes from Spring security FAQs: I'm using Tomcat (or some other servlet container) and have enabled HTTPS for my login page, switching back to HTTP afterwards. It doesn't work - I just end up back at the login page after authenticating. This happens because sessions created under HTTPS, for which the session cookie is marked as “secure”, cannot subsequently be used under HTTP. The browser will not send the cookie back to the server and any session state will be lost (including the security context information). Starting a session in HTTP first should work as the session cookie won't be marked as secure.

  • Multlingual redirect

    - by israkir
    I want to ignore the post form in the django's internatonalization. I am using the django-multilingual app, so I have different fields for different languages in the db. I come up with this idea: For each language, from the index.html page, redirect to a different url (e.g. /en/ or /de/ or /zh/). And each view of this urls, set the session according to the language like this: def set_lang_en(request): request.session['django_language'] = 'en' render_to_response("home.html") def set_lang_zh(request): request.session['django_language'] = 'zh-cn' render_to_response("home.html") Interestingly, this does the job, but if i refresh the page again after redirection (home.html). Why it is like this? And how can solve this problem either in my direction or other one?

  • Question regarding Ajax Hacking

    - by Vincent
    All, I have a PHP website written in Zend Framework and MVC. Most of the controller actions check if the request is an Ajax request or not, else they redirect the user to home page. I am thinking about various ways to break that site. I am considering the following scenario: A user creates his own PHP project on his Local machine. User writes a JQuery ajax post request to one of the controllers on my site and tries to post malicious info. Ex: $.ajax({ type: 'POST', url: "https://marketsite/getinfo/getstuff", cache: false, dataType: "html", success: function(html_response){ alert(html_response); }, error: function(xhr,ajaxOptions,errorThrown){ alert(errorThrown); } }); My Question is does "url" attribute in the ajax request above take absolute path? I know it takes relative path. Also, is it possible to break any site by sending such requests? Thanks

  • Why is my NSURLConnection so slow?

    - by Bama91
    I have setup an NSURLConnection using the guidelines in Using NSURLConnection from the Mac OS X Reference Library, creating an NSMutableURLRequest as POST to a PHP script with a custom body to upload 20 MB of data (see code below). Note that the post body is what it is (line breaks and all) to exactly match an existing desktop implementation. When I run this in the iPhone simulator, the post is successful, but takes an order of magnitude longer than if I run the equivalent code locally on my Mac in C++ (20 minutes vs. 20 seconds, respectively). Any ideas why the difference is so dramatic? I understand that the simulator will give different results than the actual device, but I would expect at least similar results. Thanks const NSUInteger kDataSizePOST = 20971520; const NSString* kServerBDC = @"WWW.SOMEURL.COM"; const NSString* kUploadURL = @"http://WWW.SOMEURL.COM/php/test/upload.php"; const NSString* kUploadFilename = @"test.data"; const NSString* kUsername = @"testuser"; const NSString* kHostname = @"testhost"; srandom(time(NULL)); NSMutableData *uniqueData = [[NSMutableData alloc] initWithCapacity:kDataSizePOST]; for (unsigned int i = 0 ; i < kDataSizePOST ; ++i) { u_int32_t randomByte = ((random() % 95) + 32); [uniqueData appendBytes:(void*)&randomByte length:1]; } NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; [request setURL:[NSURL URLWithString:kUploadURL]]; [request setHTTPMethod:@"POST"]; NSString *boundary = @"aBcDd"; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; NSMutableData *postbody = [NSMutableData data]; [postbody appendData:[[NSString stringWithFormat:@"--%@\nContent-Size:%d",boundary,[uniqueData length]] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithFormat:@"\nContent-Disposition: form-data; name=test; filename=%@", kUploadFilename] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithString:@";\nContent-Type: multipart/mixed;\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[NSData dataWithData:uniqueData]]; [postbody appendData:[[NSString stringWithFormat:@"--%@\nContent-Size:%d",boundary,[kUsername length]] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithFormat:@"\nContent-Disposition: inline; name=Username;\n\r\n%@",kUsername] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithFormat:@"--%@\nContent-Size:%d",boundary,[kHostname length]] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithFormat:@"\nContent-Disposition: inline; name=Hostname;\n\r\n%@",kHostname] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithFormat:@"\n--%@--",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [request setHTTPBody:postbody]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; if (theConnection) { _receivedData = [[NSMutableData data] retain]; } else { // Inform the user that the connection failed. } [request release]; [uniqueData release];

  • Failed to load resource: the server responded with a status of 406 (Not Acceptable)

    - by skip
    I am trying to send json data and get back json data as well. I've <annotation-driven /> configured in my servlet-context.xml and I am using Spring framework version 3.1.0.RELEASE. When I send the request the browser tells me that it is not happy with the data returned from the server and gives me 406 error. And when I see the response from the server I see the whole 406 page returned by tomcat 6 server. I have got following in my pom for Jackson/Jackson processor: <!-- Jackson --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-core-asl</artifactId> <version>1.9.4</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.4</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-xc</artifactId> <version>1.9.4</version> </dependency> <!-- Jackson JSON Processor --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.8.1</version> </dependency> Following is the jquery code I am using to send the json request: $(function(){$(".sutmit-button").click(function(){ var dataString=$("#app-form").serialize(); $.ajax({ type:"POST", url:"apply.json", data:dataString, success:function(data, textStatus, jqXHR){ console.log(jqXHR.status); console.log(data); $('.postcontent').html("<div id='message'></div>"); $('#message').html("<h3>Request Submitted</h3>").append("<p>Thank you for submiting your request.</p>").hide().fadeIn(1500,function(){$('#message');}); }, error:function(jqXHR, textStatus, errorThrown) { console.log(jqXHR.status); $('.postcontent').html("<div id='message'></div>"); $('#message').html("<h3>Request failed.</h3>").hide().fadeIn(1500,function(){$('#message');}); }, dataType: "json" }); return false;});}); Following is the Controller that is handling the request: @RequestMapping(method = RequestMethod.POST, value="apply", headers="Accept=application/json") public @ResponseBody Application processFranchiseeApplicationForm(HttpServletRequest request) { //... Application application = new Application(...); //... logger.debug(application); return application; } I am not able to figure out the reason why I might be getting this error. Could someone help me understand why am I getting the given error? Thanks.

  • Passing arguments to anonymous inner classes

    - by synic
    I'm trying to make an API library for our web services, and I'm wondering if it's possible to do something like this: abstract class UserRequest(val userId: Int) { def success(message: String) def error(error: ApiError) } api.invokeRequest(new UserRequest(121) { override def success(message: String) = { // handle success } override def error(error: ApiError) = { // handle the error } } I'm talking about passing parameters to the anonymous inner class, and also overriding the two methods. I'm extremely new to Scala, and I realize my syntax might be completely wrong. I'm just trying to come up with a good design for this library before I start coding it. I'm willing to take suggestions for this, if I'm doing it the completely wrong way, or if there's a better way. The idea is that the API will take some sort of request object, use it to make a request in a thread via http, and when the response has been made, somehow signal back to the caller if the request was a success or an error. The request/error functions have to be executed on the main thread.
