  • Why does multiple sessions started on the same page gets the same session id?

    - by Calmarius
    I tryed the following: <?php session_name('user'); session_start(); // sets an 'user' cookie with session id. // This session stores the user's login data. // Its an ordinary session. $USERSESSION=$_SESSION; // saving this session $userSessId=session_id(); session_write_close(); //closing this session session_name('chatroom'); session_start(); // set a 'chatroom' cookie but contains the same session id and points to the same data :( . // This session would be used to store the chat text. This session would be // shared between all users joined in this chat room by setting the same session id for all members. // by calling session_regenerate_id would make a diffent session id for every user and it won't be a chat room anymore. ?> So I want to do a chat like thing with sessions. On the client side it would be done with ajax that polls this php page in every 5-10 seconds. Sessions may be cached in the server's memory so it can be accessible fast. I can store the chat in the database but my service runs on a free webhost which is limited, only 4 mysql connections allowed at a time which is almost nothing. I try to touch my database as least times as possible.

  • Strategy for developing a multi function asp.net web application

    - by user247023
    I'm about to start a new project and want some advice on how to implement. I need a web application which contains a booking module for reserving timeslots, and a time management module which will enable employees to clock in / clock out. If I am writing an update to the time managment module, I don't want to disrupt the booking engine availability by releasing a new solution containing both modules. to make things more difficult, there is some shared functionality like common users, roles and security. Here's a suggestion I've gotten, which sounds a bit cruddy, but may be functional. Write a 'container' web application which consists of basically a frame, and authentication / security features. This then has links which, will load the 2 independantly built and released web applications into the frame. I can see that say, if I wanted to update the time management module, I would only need to build and release this separately, and the rest of the solution would be 'untouched' Any better alternatives?

  • php not redirecting

    - by NSchulze
    I'm trying to write the logout of a website. When I do this I want the page to redirect to the login page. I think I'm doing it the correct way, but can't get the right result. Could you guys point me in the right direction? Relevant Code: <button onclick="logout()">Logout</button> function logout() { var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.location=xmlhttp.responseText; } } xmlhttp.open("GET","logout.php",true); xmlhttp.send(); } <?php session_destroy(); header("Location:http://localhost:8888/loginns.html"); mysql_close($con); ?> Thanks!

  • Administrator account: Where, when and how?

    - by Pickels
    Where, when and how to insert/create the administrator account for a website? Here are a few ways I encountered in other websites/webapplication. Installation wizard: You see this a lot in blog software or forums. When you install the application it will ask you to create an administrator user. Private webapplication will most likely not have this. Installation file: A file you run to install your application. This file will create the administrator account for you. Configuration files: A configuration file that holds the credentials for the administrator account. Manually insert it into a database: Manually insert the administrator info into the database.

  • Which Java web frameworks provide hot-reload?

    - by Stefane Fermigier
    I'd like to know which Java web application frameworks do provide a "hot reload" capability, i.e. allow to develop applications and have them redeployed on the server "almost instantly" (i.e. in less than a few seconds). I the Java world, Play! has it out of the box, but what I'm looking for is a more exhaustive list. Other examples that I'm aware of include: Nuxeo WebEngine, provided you're using Eclipse and the right plugin, or, in the Python world, Django and Pylons (when using the "--reload" option).

  • require_owner code to limit controller actions not recognizing current user as owner

    - by bgadoci
    I am trying to restrict access to certain actions using a before_filter which seems easy enough. Somehow the ApplicationController is not recognizing that the current_user is the owner of the user edit action. When I take the filter off the controller correctly routes the current_user to their edit view information. Here is the code. Link to call edit action from user controller (views/questions/index.html.erb): <%= link_to "Edit Profile", edit_user_path(:current) %> ApplicationController (I am only posting the code that I think is affecting this but can post the whole thing if needed). class ApplicationController < ActionController::Base def require_owner obj = instance_variable_get("@#{controller_name.singularize.camelize.underscore}") # LineItem becomes @line_item return true if current_user_is_owner?(obj) render_error_message("You must be the #{controller_name.singularize.camelize} owner to access this page", root_url) return false end end and the before_filter class UsersController < ApplicationController before_filter :require_owner, :only => [:edit, :update, :destroy] #... end I simply get the rendering of the error message from the ApplicationController#require_owner action.

  • How to get an internship with a low GPA?

    - by Jason Baker
    A lot of changed majors and some other mitigating circumstances have left me with a pretty low GPA. My GPA in the last couple of semesters hasn't been stellar, but my grades have gotten a LOT better. I want to try and start putting in some resumes to get a good internship this summer. I do think that I have some decent experience for someone at my level, but I see my GPA being a pretty big potential stumbling block. Is there anything I can do to help my chances of getting a good internship? (For the record, the mitigating circumstances aren't something I'd feel comfortable discussing with a potential employer. I'd prefer getting a job by proving my merit, not making excuses.)

    Hi There, When I try to run my site it gives error as Internal Server error, when I refresh the page I get my result properly.The error page looks like this: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request.

  • How RPG characters are made

    - by user365314
    If RPG with the ability to change armors and clothes are made, how is it done? I mean the 3d side mostly If i make normal character, that has flat clothes, it would be easy, just change textures, but question is about armors, which have totally different models. So are only armor models recreated or character model with armor? How is it imported into game engine, only armor or character model with new armor? If person changes armor in game, will game swap the hole model or only the armor part? if only the armor part, then how the movement animations are done, are armor models animated on characters in 3d programs or what... :D

Has anyone encountered this problem?

  • jQuery ajax form submit - how to ensure dynamically loaded form's action is used

    - by kenny99
    Hi, i'm having a problem with dynamically loaded forms - instead of using the action attribute of the newly loaded form, my jquery code is still using the action attribute of the first form loaded. I have the following code: //generic ajax form handler - calls next page load on success $('input.next:not(#eligibility)').live("click", function(){ $(".form_container form").validationEngine({ ajaxSubmit: true, ajaxSubmitFile: $(this).attr('action'), success : function() { var url = $('input.next').attr('rel'); ajaxFormStage(url); }, failure : function() { } }); }); But when the next form is loaded, the above code does not pick up the new action attribute. I have tried adding the above code to my callback on successful ajax load (shown below), but this doesn't make any difference. Can anyone help? Many thanks function ajaxFormStage(url) { var $data = $('#main_body #content'); $.validationEngine.closePrompt('body'); //close any validation messages $data.fadeOut('fast', function(){ $data.load(url, function(){ $data.animate({ opacity: 'show' }, 'fast'); '); //generic ajax form handler - calls next page load on success $('input.next:not(#eligibility)').live("click", function(){ $(".form_container form").validationEngine({ ajaxSubmit: true, ajaxSubmitFile: $(this).attr('action'), success : function() { var url = $('input.next').attr('rel'); ajaxFormStage(url); }, failure : function() { } }); }); }); });

  • How to remove proxy from WebRequest and leave DefaultWebProxy untouched

    - by Elephantik
    I use FtpWebRequest to do some FTP stuff and I need to connect directly (no proxy). However WebRequest.DefaultWebProxy contains IE proxy settings (I reckon). WebRequest request = WebRequest.Create("ftp://someftpserver/"); // request.Proxy is null here so setting it to null does not have any effect WebResponse response = request.GetResponse(); // connects using WebRequest.DefaultWebProxy My code is a piece in a huge application and I don't want to change WebRequest.DefaultWebProxy because it is global static property and it can have adverse impact on the other parts of the application. Any idea how to do it?

  • Self-signed ceritificates for many users/browsers/sites

    - by Demiurg
    Here is my problem - I have a lot of users using different browsers accessing many internal web sites using https. I can create my own Certificate Authority, than create a certificate for each server and after that have all the users import it. Obviously, it cannot work in reality - there are too many users and too many sites, and some sites will be added in the future. I'm looking for a way to automate this. Is there a way to create a certificate so that all major browsers (IE, FF, Opera, Chrome and Safari) would trust it for all servers ? If so, what is the best way to install it automatically in all major browsers ?

  • Restful Path Parameters in Spring MVC 3

    - by MDK
    Is it possible to: set a URI template in the mvc:view-controller element of the *-servlet.xml file or in a controller method and then use/get that path parameter in a jsp? I understand that using @PathVariable in a controller method will give me access to the path parameter in that controller method. But how can I gain access to the path parameter in the jsp? For example, is it possible to do something like: *-servlet.xml file: <beans...> <mvc:view-controller path="/home" view-name="home"/> <mvc:view-controller path="/home/{error}" view-name="home"/> </beans> jsp file: <c:if test="${not empty param['error']}"> <span class="error">You have an error...</span> </c:if>

  • Portable Programming IDE

    - by Click Ok
    Frequently I'm brainstormed with programming ideas that I would like to directly code. More or less like "Wow, that algorithm will rock! I need to write it now!". For this kind of "impulse" to write, I use http://www.jarte.com/ that is a cool portable text editor. If I'm near a cybecafe or a friend computer, I just plug the usb pen drive and start to write... So, I would like: 1) a portable minimalist IDE 2) with minimal OS requirement (ie.: I want run from XP, Vista, etc...) 3) any modern language (I can learn a new language if needed. I just want write/test the algoritm) 4) Syntax Highlight/intellisense is good, but not required 5) Free Is there something like this?
