  • Would dynamically created JavaScript files be cached?

    - by venksster
    So my application uses a LOT of js files. thats a lot of http requests. I decided to combine them dynamically at the server in packs of 3-4 files clubbed by functionality. My client side request is: ...script type="text/javascript" src="http://mydomain.com/core-js.php" ... My server side does: --core-js.php-- header("Content-type: application/x-javascript"); include_once('file1.js'); include_once('file2.js'); include_once('file3.js'); include_once('file4.js'); I am setting a far future expire header on core-js.php. My question is, would core-js.php be cached at the client side? If it would be, could someone please explain how? Thanks!

  • Is there a Java Package for testing RESTful APIs?

    - by Zachary Spencer
    I'm getting ready to dive into testing of a RESTful service. The majority of our systems are built in Java and Eclipse, so I'm hoping to stay there. I've already found rest-client (http://code.google.com/p/rest-client/) for doing manual and exploratory testing, but is there a stack of java classes that may make my life easier? I'm using testNG for the test platform, but would love helper libraries that can save me time. I've found http4e (http://www.ywebb.com/) but I'd really like something FOSS.

  • Comet with ASP.NET AsyncHttpHandlers

    - by Sumit
    I am implementing a comet using AsyncHttpHandlers in my current asp.net application. According to my implementation client initially sends Notification Hook request to server (with its user id) on AsyncHttpHandler, and on server side I maintain a Global (Application level) dictionary of userid(key) and IAynsResult (value). So when ever a request is received to send notification to a user I just pick the matching IAsyncResult from the Global Dictionary and send response to the client user. My concern is, is maintaing a Dictionary of Userid and IAsyncResult at Application level a good design? I feel it will put a lot of load on the server, at the time of high traffic. Is there any other way I can achieve the comet. or what will be the good design to achieve comet for high traffic scenarios.

  • Huge amount of time sending data with suds and proxy

    - by Roman
    Hi everyone, I have the following code to send data through a proxy using suds: import suds t = suds.transport.http.HttpTransport() proxy = urllib2.ProxyHandler({'http': 'http://192.168.3.217:3128'}) opener = urllib2.build_opener(proxy) t.urlopener = opener ws = suds.client.Client('http://xxxxxxx/web.asmx?WSDL', transport=t) req = ws.factory.create('ActionRequest.request') req.SerialNumber = 'asdf' req.HostName = 'hola' res = ws.service.ActionRequest(req) I don't know why, but it can be sending data above 2 or 3 minutes, or even more and it raises a "Gateway timeout" exception sometimes. If I don't use the proxy, the amount of time used is above 2 seconds or less. Here is the SOAP reply: (ActionResponse){ Id = None Action = "Action.None" Objects = "" } The proxy is running right with other requests through urllib2, or using normal web browsers like firefox. Does anyone have any idea what's happening here with suds? Thanks a lot in advance!!!

  • Convert ASP.NET membership system to secure password storage

    - by wrburgess
    I have a potential client that set up their website and membership system in ASP.NET 3.5. When their developer set up the system, it seems he turned off the security/hashing aspect of password storage and everything is stored in the clear. Is there a process to reinstall/change the secure password storage of ASP.NET membership without changing all of the passwords in the database? The client is worried that they'll lose their customers if they all have to go through a massive password change. I've always installed with security on by default, thus I don't know the effect of a switchover. Is there a way to convert the entire system to a secure password system without major effects on the users?

  • Searching for patterns to create a TCP Connection Pool for high performance messaging

    - by JoeGeeky
    I'm creating a new Client / Server application in C# and expect to have a fairly high rate of connections. That made me think of database connection pools which help mitigate the expense of creating and disposing connections between the client and database. I would like to create a similar capability for my application and haven't been able to find any good examples of how to apply this pattern. Do I really need to spin up an instance of a TcpClient every time I want to send a message to the server and receive a receipt message? Each connection is expected to transport between 1-5KB with each receiving a 1KB response message. I realize this question is somewhat vague, but I am starting from scratch so I am open to suggestions. Even if that means my suppositions are all wrong.

  • NHibernate cascade and inverse

    - by Kordonme
    I have three mappings as follows: public MainChapterMap() { // other properties HasMany(x => x.ClientSpecific).KeyColumn("MainChapterId"); } public MainChapterClientMap() { // other properties References(x => x.MainChapter).Column("MainChapterId"); HasMany(x => x.Details).KeyColumn("MainChapterClientId"); } public MainChapterClientDetailMap() { // other properties References(x => x.MainChapterClient).Column("MainChapterClientId"); } MainChapter has many client-specific chapters. The client-specific chapters (MainChapterClient) has many translations (MainChapterClientDetail) The dele rules should be as follow: When deleting a MainChapter Delete the MainChapterClient row Delete the MainChapterClientDetail row(s) When deleting a MainChapterClient Do NOT delete the MainChapter row Delete the MainChapterClientDetail row(s) When deleting a MainChapterClientDetail Do NOT delete the MainChapter row Do NOT delete the MainChapterClientDetail row(s) But I no matter what I end up getting this error: deleted object would be re-saved by cascade (remove deleted object from associations)[Entities.MainChapterClient#39] I'm not sure how to set up my cascades anymore. Any help are more than welcomed!

  • Properties in Remoting

    - by Evl-ntnt
    Server: Host h = new Host(); h.Name = "JARR!!"; TcpChannel channel = new TcpChannel(8080); ChannelServices.RegisterChannel(channel); RemotingConfiguration.RegisterWellKnownServiceType(typeof(Host), "Server", WellKnownObjectMode.Singleton); Client: TcpChannel chan = new TcpChannel(); ChannelServices.RegisterChannel(chan); remoteHost = (Host)Activator.GetObject(typeof(Host), "tcp://127.0.0.1:8080/Server"); Class: [Serializable] public class Host: MarshalByRefObject { public string Name{get; set;} public Host(){} public Host(string n) { Name = n; } public override string ToString() { return Name; } } Connection OK, 8080 port opened, on client side remoteHost is not null, but remoteHost.Name == "" Why?

  • What if I have an API method and a contoller/view method with the same name in RoR?

    - by Chad Johnson
    Suppose I want to be able to view a list of products on my site by going to /product/list. Great. So this uses my 'list' view and outputs some HTML which my web browser will render. But now suppose I want to provide a REST API to my client where they can get a list of their products. So I suppose I'd have them authenticate with oAuth and then they'd call /product/list which would return a JSON array of their products. But like I said earlier, /product/list displays an HTML web page. So, I have a conflict. What is normal practice as far as providing APIs in Rails? Should I have a subdirectory, 'api', in /app/controller, and another 'product' controller? So my client would go to /api/product/list to get a list of their products? I'm a bit new to RoR, so I don't have the best grasp of the REST functionality yet, but hopefully my question makes sense.

  • Simple Windows.Forms binding is failing using framework 4.0.

    - by jyoung
    This works under the .net framework 3.5 client. This fails under the .net framework 4.0 client. Was I doing something that was illegal under 3.5 but just happened to work, or is this a bug? Note that in my project 'PropInt' does not raise change events so using ctx[obj1.PropObj2, "PropInt"] is not an option. public class Obj1 { public Obj2 PropObj2 { get; set; } public Obj1() { PropObj2 = new Obj2(); } } public class Obj2 { public int PropInt { get; set; } } static class Program { [STAThread] static void Main() { var ctx = new BindingContext(); var obj1 = new Obj1(); var x1 = ctx[obj1, "PropObj2.PropInt"]; } }

  • JAX-WS: when input soap validation fails

    - by Jakob
    I have created a web service with JAX-WS. When the input SOAP message is not well formed or can not be validated, a soap fault is returned automatically to the caller. I dont want the caller to receive this standard SOAP message but i want to create an own custom SOAP fault. So if the call looks like this (note Envelope1, its not valid): hello a default return message is something like this: S:Client Couldn't create SOAP message due to exception: unexpected XML tag. expected: {http://schemas.xmlsoap.org/soap/envelope/}Envelope but found: {http://schemas.xmlsoap.org/soap/envelope/}Envelope1 I want the return message to be something like this: S:Client My own custom SOAP message! I have tried to get this to work the whole day, but i cant figure out how to do it. So if someone could help me I would be really glad!

  • How to set RequestBody for Http Delete method.

    - by Tushar Tarkas
    I am writing a client code for a server which Delete API. The API specification requires data to be sent. I am using HttpComponents v3.1 library for writing client code. Using the HtpDelete class I could not find a way to add request data to it. Is there a way to do so ? Below is the code snippet. HttpDelete deleteReq = new HttpDelete(uriBuilder.toString()); List<NameValuePair> postParams = new ArrayList<NameValuePair>(); postParams.add(new BasicNameValuePair(RestConstants.POST_DATA_PARAM_NAME, postData.toString())); try { UrlEncodedFormEntity entity = new UrlEncodedFormEntity(postParams); entity.setContentEncoding(HTTP.UTF_8); //deleteReq.setEntity(entity); // There is no method setEntity() deleteReq.setHeader(RestConstants.CONTENT_TYPE_HEADER, RestConstants.CONTENT_TYPE_HEADER_VAL); } catch (UnsupportedEncodingException e) { logger.error("UnsupportedEncodingException: " + e); } Thanks in advance.

  • How to translate,use JSON in GWT?

    - by graybow
    I'm new in gwt. and need to know how to use JSON in gwt so i try this simple data loader but i'm still confuse. I create a project named 'tesdb3' in eclipse. I create the PHP side to access the database, and made the output as JSON.. I create the userdata.php in folder war. then I compile tesdb3 project. Folder tesdb3 and the userdata.php in war moved in local server(I use WAMP). I put the PHP in folder tesdb3. This is the result from my localhost/phpmyadmin/tesdb3/userdata.php [{"kode":"002","nama":"bambang gentolet"}{"kode":"012","nama":"Algiz"}] From that result I think the PHP side was working good.Then I create UserData.java as JSNI overlay like this: package com.tesdb3.client; import com.google.gwt.core.client.JavaScriptObject; class UserData extends JavaScriptObject{ protected UserData() {} public final native String getKode() /*-{ return this.kode; }-*/; public final native String getNama() /*-{ return this.nama; }-*/; public final String getFullData() { return getKode() + ":" + getNama(); } } Then Finally in the tesdb3.java: public class Tesdb3 implements EntryPoint { String url= "http://localhost/phpmyadmin/tesdb3/datauser.php"; private native JsArray<UserData> getuserdata(String Json) /*-{ return eval(json); }-*/; public void LoadData() throws RequestException{ RequestBuilder builder = new RequestBuilder(RequestBuilder.POST, URL.encode(url)); builder.sendRequest(null, new RequestCallback(){ @Override public void onError(Request request, Throwable exception) { Window.alert("error " + exception); } public void onResponseReceived(Request request, Response response) { getuserdata(response.getText()); //this is how i use the userdata json(is this already translated?) UserData UD = null; String LKode =UD.getKode(); String LName =UD.getNama(); Label L = new Label(LKode+""+LName); RootPanel.get().add(L); } }); } public void onModuleLoad() { try { LoadData(); } catch (RequestException e) { e.printStackTrace(); } } } The result is blank(i use development mode). and there was an eror like this:(I show it just some part) 10:46:29.984 [ERROR] [tesdb3] Uncaught exception escaped com.google.gwt.core.client.JavaScriptException: (ReferenceError): json is not defined fileName: http://localhost:1092 lineNumber: 2 stack: ("")@http://localhost:1092:2 My question is: How I use the translated Json in right way?? Is there any wrong use from my code? Is that necessary to move the compiled project to local server folder?(i do it following a tutorial from google). Sorry too many ask. but i'm really really confused.

  • Displaying Powerpoint slides on a web page automatically

    - by Jamie
    Anyone know of any Flash components that would do the job of displaying an external PPT/PPTX file in a Flash movie on a web page? Or a way of automatically parsing uploaded Powerpoint docs from a PHP-based CMS and displaying them on a web page. Our client needs to be able to upload a Powerpoint documents on their site without any intervention (if necessary). I know about Slideshare and the like, but the content needs to live on the client's web server due to security restrictions. Also, Adobe Presenter seems to require Adobe software/plugins on the clients machine which wouldn't be ideal. Thanks in advance

  • ASP.NET WebMethod Returns JSON wrapped in quotes

    - by CL4NCY
    Hi, I have an asp.net page with a WebMethod on it to pass JSON back to my javascript. Bellow is the web method: [WebMethod] public static string getData(Dictionary<string, string> d) { string response = "{ \"firstname\": \"John\", \"lastname\": \"Smith\" }"; return response; } When this is returned to the client it is formatted as follows: { \"d\": \"{ \"firstname\": \"John\", \"lastname\": \"Smith\" }\" } The problem is the double quotes wrapping everything under 'd'. Is there something I've missed in the web method or some other means of returning the data without the quotes? I don't really want to be stripping it out on the client everytime. Also I've seen other articles where this doesn't happen. Any help would be appreciated thanks.

  • Stream post URL security and wall post links

    - by Jeff Lee
    Our app's mobile client can create wall post links to our app's web-facing pages. Since this happens in the context of a mobile app, we do this on behalf of our user using the Graph API's feed/message endpoint. I noticed that the links showing up in the wall posts are being routed through our app's auth dialog, which is NOT what we want. We just want transparent links, without forcing the client to auth our app, similar to what happens when you share to FB in Path. I went ahead and disabled the "Stream post URL option" several hours ago, but we still seem to be getting the re-routed links for wall posts. The target URLs for these links are within the domain we've registered for our Facebook app. Is there anything else I need to do fix this?

  • Is there any way to create a dynamic list of strings (based on language) in XAML?

    - by Xin
    Just wondering if it is possible to dynamically create a list of strings in XAML based on language/culture? Say if user logs in as an English user it shows Client Name, Order Number... and if user logs in as a Polish user it shows Nazwa klienta, Numer zamówienia instead? I only know the hardcoded one like below: <System_Collections_Generic:List`1 x:Key="columnNameList"> <System:String>Client Name</System:String> <System:String>Order Number</System:String> <System:String>Date</System:String> </System_Collections_Generic:List`1>

  • Loopj Android Async Http - onFailure not fired

    - by Ashley Staggs
    I am using the great async http library from loopj, but I have run into a small snag. If the user has no internet connection or loses their connection, the app just won't return anything. This part is expected, but it also doesn't fire the onFailure method. Also, the code I have used when there is an internet connection does work so there is no problem on the server end. Here is some code that is stripped down to the minimum. It also doesn't work (I have tested this too) String url = getString(R.string.baseurl) + "/appconnect.php"; client.getHttpClient().getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true); client.get(url, null, new JsonHttpResponseHandler() { @Override public void onSuccess(JSONArray response) { Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_SHORT).show(); } @Override public void onFailure(Throwable e, JSONArray errorResponse) { Toast.makeText(getApplicationContext(), "Failure", Toast.LENGTH_SHORT).show(); } }); Thanks, Ashley

  • How to make .NET WebForm Routing work with Authorization

    - by jakmas
    I have routes that are being registered from the database into an asp.net website (non MVC). The routes register fine, they all work when I am logged in. What I am trying to do is create a landing page based on some route data: Page is [site]/landing/dell The route looks like: "landing/{client}" and it routes to my page Login.aspx, in there I get the client out of the route, then display some custom brand data based on the value. In my web.config, I have my authentication mode set to forms, with my loginUrl = "Login.aspx" When the user does not have the authorization cookie, it redirects the user to: [site]/Login.aspx?ReturnUrl=%2flanding%2fdell instead of keeping the route url, and displaying the correct data. The IIS server actually does not even process the route at all, just sends the user to the Login.aspx page. I have tried several additions to my web.config: etc, and many variations, but nothing seems to work. Ideas anyone? I assume this is a common issue, and it is just not well documented.

  • How to change the HTML text to Right-to-Left order when rendering the text within a WebBrowser.

    - by Java Doe
    hi, I am using a WebBrowser to render some HTML text. The WebBrowser is located within a rich client. I can detect the window's orientation when the rich client is launched. How do I make the text rendered within the WebBrowser to be dispayed in RTL order. I have tried body.setDir("rtl"), but it only aligned all the text in the WebBrowser to the right. It does not really reverse the content. For example, I have a photo that is displayed on the left and then a segment of text displayed on the right. After calling body.setDir("rtl"), it only aligned everything to the right in the WebBrowser, but it did not move the photo to the right, and it did not move the text to the left. Thanks a lot!

  • Parsing a list of dictionaries passed as a POST parameter

    I have a list of python dictionaries that look like this: sandwiches = [ {'bread':'wheat', 'topping':'tomatoes', 'meat':'bacon'}, {'bread':'white', 'topping':'peanut butter', 'meat':'bacon'}, {'bread':'sourdough', 'topping':'cheese', 'meat':'bacon'} ] I want to pass this as a POST parameter to another Django app. What does the client app need to do to iterate through the list? I want to do something like: for sandwich in request.POST['sandwiches']: print "%s on %s with %s is yummy!" % (sandwich['meat'], sandwich['bread'], sandwich['topping']) But I don't seem to have a list of dicts when my data arrives at my client app.

I am using communication between 2 Windows Server 2008 R2. The client and the server are coded using c#. I tryed using tcpclnt.SendBufferSize = 100000; tcpclnt.Client.DontFragment = true; and the same at the server. I also tried configuring the window size of the server(editing the registry).
