Php - Which Language Would Be Best Contents For Classified Ad High Traffic Website

Dec 25, 2010

Average visitors: 5000.

I'm wondering should i make it in PHP or ASP.NET/C#. Website contents might grow really fast because it is expected there going to be daily/continuous posts from users. Its an interactive website that has to login, post, check replies and private messages without any advanced/complex features.

Website might use AJAX as well as JQuery.

What language do you suggest me to go with?

Alternative Approach To User Management In Web Application?

Jan 28, 2010

I am using asp.net 2.0. I have been using asp.net membership provider for user management. But I think this would be more efficient if I could do this without using role and membership provider provided in asp.net.In fact I see bulky markups generated when I add login control, createuser control etc. in an asp.net web page.By saying user management, I am referring to the overall login, user activity tracking, password reset/retrieval, role management in an asp.net web application. And I want to implement efficient way to accomplish this.

C# - Finding Session Alternative In Global Scope?

Feb 24, 2011

Quick question: Is there a "per-user" data storage object (similar to Session) that I can store data in the global scope (similar to HttpRuntime.Cache)? Almost as if Session and HttpRuntime.Cache had a baby.

Full Background: I have a ASP.NET website that was originally written for a single thread. Now I changed it so that certain actions will spawn a background thread and the browser polls a service to get status updates.

The problem I am having with this is that certain pieces of data are stored into the HttpContext.Session[] object (membership authentication token, for example). These pieces of data need to be unique to each user and accessible to the background thread. Session is not available to the background thread.

I am aware of HttpRuntime.Cache but that would require micromanagement to segment out the users and to expire it at the same time the session is expired. Session, on the other hand, automatically expires this things at the right times that I want it too and is already used by things like the SqlMembershipProvider.

My question is, is there something that behaves similar to the Session but exists in the global scope?

Setting Alternative Session Expiration Times?

Jan 15, 2011

I want a specific session variable (in my case Session["level"]) to expire either on the normal 20 min. timer or at 19:30 every day. Because I change a value in my database everyday at 19:30 and I want this session variable to be related to that value. Is this possible?

C# - Setting Trust Level To High In Web.config Makes Application Run Slower?

Jan 11, 2011

We had a UAT and Production version of a .NET web application. UAT was taking around 5 seconds to run a particular operation while Prod was taking 35+ seconds.

This even happened when pointing both web applications at the same database and putting them both on the same machine.

The culprit was finally found to be the following entry, which was in the Prod but not UAT web.config

<trust level="High" originUrl="" />

why this would cause such a significant performance degradation??

SQL Server :: Unexpected Error Message When The User Volume Is High?

Nov 25, 2010

I built an asp.net application using web developer express 2008 and sql express2008. The live version hosted on Godaddy, for the most part is working well. However, occasionally the users are reporting an error when the user volume is high.

Here is part of my web.config code:

<customErrors defaultRedirect="/Error/error.htm" mode="On">
<error statusCode="400" redirect="/Error/BadRequest.htm"/>
<error statusCode="404" redirect="/Error/NotFound.htm"/>
<error statusCode="408" redirect="/Error/TimeOut.htm"/>
</customErrors>

I have seen the other error pages work correctly and the error I am referring to above is the default error.It is possible that up to 10 users opening the same database table at the same time might be the problem? Would this be a potential cause of my unknown error? And if so what can I do about it?

Java - Methods To Set A Session Token By Url?

Mar 18, 2011

I'm writing up a security document and it would be great if programmers in other languages than PHP could chime in on (perhaps the default) way sessions are passed by URL in their language's default session handler.

eg. PHPSESSION=token in PHP

Oh, and if yes does it also use cookies?

Security :: Maintain Session For Multi User Application?

Oct 25, 2010

I am developing a web application. This application is fully customised based on the user settings. Suppose, application hosted on [URL] and user can signup on the website and it will get the domain like [URL] and for user2 will be [URL] so and so forth. so in this case how would I maintain the session for each user? each user will be representing a single website along with public interface and admin pages.

what I am thinking is to store all the setting (for each user) in the database and then when ever server received request then get the user info from the URL (first time only and after get it from the session) and get user details but I am not very much satisfied with this approach.

Managing A Session With C# Website From Java (Apache HttpClient)?

Dec 13, 2010

I want to fetch a web page from a ASP.NET site that is only accessible from within a session. I'm using Apache HttpClient. I first open the main page of the site, then I search for the link to the "goal" page, and then I fire up a GET request for the "goal" page. The problem is that when I get the response for the second GET request, I always get the same (first) page. If I open the site with Firefox or Google Chrome I get the "goal" page.

From the first response from the server I get the following headers:

HTTP/1.1 200 OK
Date: Sun, 12 Dec 2010 19:03:56 GMT
Server: Microsoft-IIS/6.0
Platform: Mobitel Pla.NET
Node: 4
X-Powered-By: ASP.NET
X-AspNet-Version: 1.1.4322
Set-Cookie: ASP.NET_SessionId=0vpgd055cifko3mnw4nkuimz; path=/
Cache-Control: no-cache, must-revalidate
Content-Type: text/html; charset=utf-8
Content-Length: 7032

I inspected the traffic with WireShark and all headers look OK. I send the correct cookie back to the server on the second GET request.

I'm using Apache HttpClient. I have only one instance of DefaultHttpClient and I reuse that for the second request. I have BROWSER_COMPATIBILITY Cookie Policy.

C# - Static Behave / Only Work For A Specific User Session Or For Overall Application?

Mar 1, 2011

I have an asp.net application with c# language. I have a common class which maintain the constants and static variables and fields. I also have a login page. If the user logs in successful I set IsLoggedInSuccessfull as a static boolean variable in common class.

My question is: Will this only work for a specific user session or for overall application ?

Edited:
Based on some answers I got another question here.

let say i am using the Static method as Authenticate(User objUser). intention is to call this method when user clicked log in button. where on login button I am let say prepare the User object with certain parameters required for login, then passing to this method. what would be the impact there? let say I have single server for now (no server farm or garden). then there will be the single application level method to authenticate the user, right? and say 10000 user are going to logging in to this site/application then how authenticate() method comes in behaves ? will CLR automatically manage threading there ?

Web Forms :: Multiple Tag Appearing - User Control Alternative

Nov 17, 2010

I have user control page (.acsx file), which has following

<form action=abcd.aspx id="safsdf">
<input name="q" type="text" value="Search this site" size="13" onfocus="this.value='';"/> //this is input box
<input type="submit" name="sa" value="Submit" />
//this is input button </form>

When user click on submit button, then it postback to same page. I have another page , which reference to this user control and that is why multiple <form> tag appears on one single page and it cause my webpage to layout incorrectly. I would like to remove <form> tag from my above user control and replace with some other alternative, which does postback to same page without using <form> tag on user control (I have to remove <form> tag from user control because I must keep my <form> tag on other page).
