• Web Form based login in Java

  - by BrunoLM

  How can I block access to the site if a user is not logged in? Under web.xml Security I checked Form authentication then I selected Login and Error page, but I don't know how to block the access and redirect the user to the login page. Do I need a filter? If so, how can I get the login url I specified? And how should I call the validation method? I saw in some examples this code <form method=post action="j_security_check"> <input type="text" name="j_username" /> <input type="password" name="j_password" /> </form> What does it do?

• Cannot pass a input from text box to a query string and then keep the string in this box.

  - by Nikita Barsukov

  I have a simple ASP.net page: <form id="form1" runat="server"> <p><asp:TextBox id="input_box" runat="server"></asp:TextBox> <asp:Button Text="OK" runat="server" OnClick="run" /></p> </form> I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads. That's the code behind page: protected void Page_Load(object sender, EventArgs e) { input_box.Text = Request.QueryString["input"]; } protected void run(object sender, EventArgs e) { string url = string.Format("?input={0}", input_box.Text); Response.Redirect(Request.Url.AbsolutePath + url); } Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?

• Drupal form being rendered before submit action

  - by alxp

  I have a Drupal module page where I am populating a form with a drop-down that contains a list of available parts of a set of files that the user can upload. Once the user uploads a file of a certain type, it removes that option from the list, and when all the available files are uploaded the form will not be rendered. The problem is that Drupal is drawing the form before it carries out the submit action, so it appears to the user that the operation didn't work until they reload the page. What is the common way to deal with this? Setting form_state['redirect'] to go to the page doesn't seem to work.

• Print PDF from ASP.Net without preview

  - by nmiranda

  Hi, I've generated a pdf using iTextSharp and I can preview it very well in ASP.Net but I need to send it directly to printer without a preview. I want the user to click the print button and automatically the document prints. I know that a page can be sent directly to printer using the javascript window.print() but I don't know how to make it for a PDF. Edit: it is not embedded, I generate it like this; ... FileStream stream = new FileStream(Request.PhysicalApplicationPath + "~1.pdf", FileMode.Create); Document pdf = new Document(PageSize.LETTER); PdfWriter writer = PdfWriter.GetInstance(pdf, stream); pdf.Open(); pdf.Add(new Paragraph(member.ToString())); pdf.Close(); Response.Redirect("~1.pdf"); ... And here I am.

• Cannot get principal id on my Spock test

  - by Ant's

  I have a controller like this : @Secured(['ROLE_USER','IS_AUTHENTICATED_FULLY']) def userprofile(){ def user = User.get(springSecurityService.principal.id) params.id = user.id redirect (action : "show", params:params) } I want to test the controller above controller in spock, so I wrote a test code like this: def 'userProfile test'() { setup: mockDomain(User,[new User(username:"amtoasd",password:"blahblah")]) when: controller.userprofile() then: response.redirectUrl == "/user/show/1" } When I run my test, this test fails with this error message : java.lang.NullPointerException: Cannot get property 'principal' on null object at mnm.schedule.UserController.userprofile(UserController.groovy:33) And in case of Integration test: class UserSpec extends IntegrationSpec { def springSecurityService def 'userProfile test'() { setup: def userInstance = new User(username:"antoaravinth",password:"secrets").save() def userInstance2 = new User(username:"antoaravinthas",password:"secrets").save() def usercontroller = new UserController() usercontroller.springSecurityService = springSecurityService when: usercontroller.userprofile() then: response.redirectUrl == "/user/sho" } } I get the same error as well. What went wrong? Thanks in advance.

• How to record when user follows external links without slowing user down

  - by taw

  I want to track when user clicks external links for analytics purposes. The simplest solution is to replace all external links with links to special record-and-redirect controller, but that would slow the user unnecessarily. The second idea would be to override click event and within in $.post a message to record controller, then let the main event handler happen, which will usually be either click (open link in same tab) or middle click (open in new tab) - good either way, and the user won't have to wait for wait for my server to record it, it's fire-and-forget. (I don't care if users without Javascript don't get tracked) Is that a reasonable way to go? Or what else would be the best way to track all external link clicks?

  - by Leto

  i made a simple .htaccess file to expose the problem. I want that all request made to the folder redirect to a subfolder file "app/index.php" RewriteEngine On RewriteRule (.*) app/index.php [QSA] And this works fine on with the basic url of my hoster (like http//myname.hosting.com/htaccessFolder The problem is that i have a domain pointing on this folder, and when accessed to it, server return Internal Server Error 500.

• Google Adword not working /conversion.js not found

  - by Jed

  I'm currently working on a wordpress site. My task is just to add the conversion script in a thankyou page. I added the script here: http://www.livingedge.co.nz/thanks-for-getting-in-touch/ , unfortunately does not work. It says that a conversion.js was not found. See the attached screenshot: http://screencast.com/t/52ixQUzHKNxZ I added the conversion script on the footer put it in a conditional so that it will load only on the thakyoupage. I'm new to this and can't figure out what would be the possible cause of such problem. I tried adding the script in the header, on the page editor, on a form redirect. Q: What could be the possible cause of this issue?

• posting to aweber with jQuery

  - by wcpro

  Im trying to post to aweber using just jquery. I have a method call like this $(function () { $('#submit').click(function () { $.post('http://www.aweber.com/scripts/addlead.pl', { meta_web_form_id: '12345', meta_split_id: '', listname: 'some_list', redirect: '', meta_redirect_onlist: '', meta_adtracking: 'my_Web_Form', meta_message: '1', meta_required: 'name,email', meta_forward_vars: '', meta_tooltip: '', email : '[email protected]', name : 'tester testing' }, function (data) { alert('data load: ' + data); }); }); }); it is supposed to take the result of the post and alert it in a box. when i try to do it manually with forms it works but redirects me to a 'form-sorry.htm' page, which is fine, just wondering if there was a way to display the end result of the post. Im guessing hte addlead.pl is just a posting page with no response.

• Sharing on Facebook from public kiosk -- user can't logout from FB!

  - by user206481

  I have a website that is designed to be run at a kiosk at public events. I want users to be able to share a page from this site on Facebook without leaving their Facebook session logged in. This is not a Facebook Connect site (there's no login to synchronize w/FB), all I have is a link for sharing that goes to Facebook's sharer.php: <a href="http://www.facebook.com/sharer.php?u="http://mysite.com/mypage">share this</a> It allows the user to log in and posts the link fine, but then closes the window and leaves the user logged in. There is no option for logging out, so the next user that comes along and wants to share has the previous user's FB account logged in! Seems like this just changed when Facebook's UI changed recently; previously it would redirect to the user's profile page after posting, from which they could log out. How can I fix this? Any recommendations on the "right way" to allow sharing with FB from a public kiosk?

• How to inspect JSP request URL for String

  - by IAmYourFaja

  I have the following processor.jsp file: <% response.sendRedirect("http://buzz.example.com"); %> I want to change it so that it inspects the HTTP request URL for the presence of the word "fizz" and, if it exists, redirect the user to http://fizz.example.org instead. So something like: <% String reqUrl = request.getURL().toLowerCase(); String token = null; if(reqUrl.contains("fizz")) { token = "fizz"; } else { token = "buzz"; } String respUrl = "http://%%%TOKEN%%%.example.com".replace("%%%TOKEN%%%", token); response.sendRedirect(respUrl); %> However this doesn't work. Any ideas on what I should be using instead of request, or if I'm doing anything else wrong?

• How do I post to a webservice and display the returned Response in MVC3 Razor Application?

  - by DavieDave

  I have need to call a webservice from an HTML helper extension I created (combinbation of Action and Image) and placed in the view as follows @Html.ActionImage("CallService", new { number = ViewBag.number, code = ViewBag.code, account = ViewBag.account, amount = ViewBag.amount }, "~/Content/sb_200x61.png", "Start the Process") I am making the action call and it calls the service and returns a string of the html response, but it doesn't look right. I am using the typical HttpWebRequest to do the POST Action in C# code. Here is the controller action code: public MvcHtmlString CallService(string number, string code, string account, decimal? amount) { string response = MyService.ServiceLayer.ClassName.callService(number, code, account, Convert.ToDecimal(amount); MvcHtmlString mstring = new MvcHtmlString(response); return mstring; } When it returns the string back it's looking like the all styling and js is removed. It that due to MvcHtmlString? Is there a better way to do this? Redirect somehow ?

• .htaccess: subdomain to sub-folder

  - by Oden

  Hey, How can i redirect a subdomain call to a folder? So when the site, sub.domain.com is requested, the name of the subdomain should point to a subfolder. The server is configured to add every request to the domain, but i get a 404 page everytime i do a non-defined subdomain call (witch is trivial, because theres nothing defined) EDIT my request looks like this: sub.domain.com What and i want to get that it works like a "virtual subdomain", because it has to request a folder with the same name that the subdomain. (domain.com/sub/) So the question is: How to solve this, with .htaccess?

• I have three different websites and I want to create a single entry point for all of them but how?

  - by austin powers

  Hi all, We are creating three different websites using asp.net but for the user part we want to implement an approach so that each user only need to create an account in any of these three sites but use the same account in other websites too. here is what I've suggested : create a useracount.website.com server then put the sql server there and implement core user account library there such as (creating/editing/etc...) whenever a visitor needs to have an account or needs to login into out sites then we will redirect him to the useracount.website.com address and he/she should login from that point. and for the maintaining the user's states I've suggested to using cookies. and all of these scenarios should be implemented by asp.net and sql. please let me know with best approach cause I feel mine is not that good specially the cookie part. cheers.

• Forking Multiple Apps Under Python Subprocess

  - by noxtion

  Hello all. I have been looking through Google and SO for something that could help me solve this but I have run into a block. I am a bit new to Python but I am looking for a way to run multiple apps that will continuously run in the background. For example, I need 4 apps to start up with a param -appnum set to a different value. I would like to use python to count up and then start up a new app that will continue to run. I assumed I would use subprocess but I feel a bit overwhelmed by the documentation. I also plan to have the app print out sequences of numbers and would like to redirect this to a file. I noticed some of the SO questions talked about this, but I am a little confused on what to do. -Mike

• PHP CURL sending POST to Django app issue

  - by Felipe Pelá

  This code in PHP sends a HTTP POST to a Django app using CURL lib. I need that this code sends POST but redirect to the page in the same submit. Like a simple form does. The PHP Code: $c = curl_init(); curl_setopt($c, CURLOPT_FOLLOWLOCATION, true); curl_setopt($c, CURLOPT_URL, "http://www.xxx.com"); curl_setopt($c, CURLOPT_POST, true); curl_setopt($c, CURLOPT_POSTFIELDS, 'Var='.$var); curl_exec($c); curl_close ($c); In this case, the PHP is sending the HTTP POST, but is not redirecting to the page. He is printing the result. My URL still .php and not a django/url/ I need be redirected to the django URL with the Post like a simple form in HTML does. Any Idea? Thanks.

• Displaying objects based on if a user is logged in or not

  - by MaxMackie

  I'm learning about PHP sessions for user authentication on my website. I know how to restrict the viewing of a complete page using sessions (simply check if the 'uid' session variable is set and if it is, show content, if not redirect to an error). However I'm trying to figure out the best way to selectively show and hide different objects (div, text, images) based on if a user is logged in or not. Is it as simple as checking for the 'uid' session variable and displaying based on if it set or not? Is there a more efficient way of doing this id there are a lot of conditional elements on a page?

• Mod_rewrite not working properly

  - by James P

  I have this in my .htaccess file... RewriteEngine on RewriteRule ^/invite$ /invite.html It's meant to let a user access this url: http://mysite.com/invite and display the invite.html page. I don't want to redirect the user, but just show them the invite.html page from a better looking URL. When I browse to http://mysite.com/invite though, I get a 404 not found error. Is there anything I'm doing wrong? I've tried looking at tutorials for using mod_rewrite but I seem to be doing what they're telling me too... Thanks!

• Send 404 when requesting index.php through .htaccess?

  - by Daniel

  I've recently refactored an existing CodeIgniter application to use url segments instead of query strings, and I'm using a rewriterule in htaccess to rewrite stuff to index.php: RewriteRule ^(.*)$ /index.php/$1 [L] My problem right now is that a lot of this website's pages are indexed by google with a link to index.php. Since I made the change to use url segments instead, I don't care about these google results anymore and I want to send a 404 (no need to use 301 Move permanently, there have been enough changes, it'll just have to recrawl everything). To get to the point: How do I redirect requests to /index.php?whatever to a 404 page? I was thinking of rewriting to a non-existent file that would cause apache to send a 404. Would this be an acceptable solution? How would the rewriterule for that look like? edit: Currently, existing google results will just cause the following error: An Error Was Encountered The URI you submitted has disallowed characters.

• How do I rewrite a request by hostname unless it is a specified value?

  - by Tim

  My app will have a regular domain - let's say example.com - which will have information about logging in, signing up, etc. It will also host numerous other domains dynamically. My app serves the webpage for these at http://example.com/site/foobar.com/ So, I need to redirect all requests where the hostname is not example.com to /site/[hostname]/ I'm writing this in Django and hosting with Apache. How do I set up a rewrite rule to do this? The user must not know they are on any other site but foobar.com and if the user browses to foobar.com/something - the URL must be rewritten to /site/foobar.com/something
