Authentication popup in the middle of asp.net page process

Posted By:      Posted Date: October 24, 2010    Points: 0   Category :ASP.Net


I have problem where i get authentication popup rises in the middle of the page process. Let me explain the scenario in detail.

I have an asp.net application developed and hosted in intranet which is used by finance team for some monthly calculation purpose.

Since it involves calculation of huge data i just did the calculation process alone with multithreading concept and implemented the same. 

When we tried in our local and System testing environment we achieved the results in great success as the calculation took 6 minutes instead of normal 22 minutes and we happily proceded for production movement but we got stuck up in production environment with the following issue.

The moment we hit the calculation run button it started calculating and exactly after 5 mins we got a popup for authentication (it uses windows authentication) and if we give credentials it went to session timeout page. 

We thought session timeout might be an issue and we increased all the timeouts as far as we know:

 - Session timeout (gave 30 mins)

 - HTTP runtime execution timeout (1000 secs)

 - Connection timeout (sql) (300 secs)

 - Command Timeout (300 secs)

The application is hosted with the following environment

 - Windows server 2008

 - MS SQ

How to process data AFTER page is completely loaded for the user?


I have some logging that has to be done, which are some database update or inserts.

However this logging is of no importance to the user, so I only want to process the data/logs after the page is completed for the user.
As of now, if I process the data while the page is loading, I go from 1.4 to 2.0 speed (server side time processing of code), which is quite a bit comparing it is of no use to the user.

So I want this code only executed after that the page is complete.

I've been checking out Ajax, async pages etc, but the problem is it still gets executed before the page is rendered to the client, which means the client will have to wait longer then it is not being processed.

I've been checking out Threadpool.queueBackgroundWorker, however if I get it correct, this will still be executed before the page is shown to the user, as it has to complete before the prerender.

Then I thought about creating a new thread, and do the processing there, which would not have my page waiting to complete the data/logging.
However when I have 100 or 200 users loading pages at the same time, then that would mean I would be creating 200 threads on those loads, which I doubt will be good for performance. So if I want to solve this, I would have to create my own threadpool and only assign for example a max of 40 threads to it which can pr

Form based authentication Sharepoint 2007 gets redirected to login page

Hi We have sharepoint 2007 site deployed on Windows server 2008, IIS 7.0.  We extended the web application to enable forms based authentication referring to link http://msdn.microsoft.com/en-us/library/bb975136(office.12).aspx#MOSS2007FBAPart1_Intro, we selected Kerberos instead of NTLM, behavior is like, when user tries to login into the site using OOB login.aspx, user again gets redirected to the login page. We tried to extend the web application again but this time we selected NTLM, but this time farm account (also is application pool identity) is not able login and exhibits same behavior as above, but for other users we are able to login. Has anyone come across this behavior? can anyone please guide me in correct the behavior? Regards, RK  Radhakrishna

Forms Authentication sending user to LoginURL on first hit of page even though page has [allow users

On the first hit, and only the first hit, to my page having [ALLOW users="*"] in the web.config, the user is redirected to the LoginUrl, but on all subsequent visits to the page, the user IS allowed access.  The user shoud ALWAYS be allowed access to this page.  I suspect it is a configuration problem, so here are snippets of my web.config... <compilation debug="false" strict="true" explicit="true" /> <trace enabled="false"/> <authentication mode="Forms"> <forms protection="All" cookieless="UseCookies" requireSSL="false" slidingExpiration="false" timeout="20" name="12345678-1234-1234-1234-123456789012" loginUrl="~/Web/Login.aspx" defaultUrl="~/Web/MyPage.aspx" enableCrossAppRedirects="false" /> <authentication> <httpCookies httpOnlyCookies="true" /> <sessionState cookieless="UseCookies" />         <location path="Web/Contact.aspx"> <system.web> <authorization> <allow users="*"/> <authorization> <system.web> <location>   Can you help me figure out why users are not ALWAYS allowed access to the /Web/Contact.aspx page? Thx!

Forms Authentication shared between 2 Applications, but still getting directed to login page

my scenario is: Single Sign-on Within a Sub Domain (two virtual directories under the same sub domain)I've setup both sites using the same forms authentication info in my web.config. both sites have the same machine key's as well. I sign into site1. i click a link that directs to site2. site2 still redirects me to the login page, however on the login page I test HttpContext.Current.User.Identity.IsAuthenticated and it returns true. I also tested on site2's login page to pull the ticket's information and it's pulling everything. so it looks like SSO is working as far as sharing the authentication ticket, yet I cannot figure out why it still puts me on the login page? site 1: https://mysub.mydomain.com/site1/ link in site1 that directs to site2: site 1: https://mysub.mydomain.com/site2/mypage.aspx any ideas? appreciate any help someone could give.

Forms Based Authentication - problem with custom master page and login page



I have successfully enabled and set up FBA (Forms Based Authentication) on my SharePoint 2010 Foundation server. The thing is that I need to customize the look and feel of the login page. I have successfully customized the page (and master page) to look the way I want, however, when I try to log in, I get the following error/message on the page:
"Forms Based Authentication on classic Web applications has been deprecated".

What I've done:
Made copies of /_layouts/simple.master and /_layouts/login.aspx and renamed the copies. The markup in the master page is MUCH simpler than the original, but I've kept all the ContentPlaceholders that I don't use (most of them) in a hidden <asp:Panel at the bottom of the page.

I've changed the web.config file:
<authentication mode="Forms">
      <forms loginUrl="/_layouts/loginCustom.aspx" />

So, I'm not getting any errors on the page until I try to log in. When I use the default settings (login.aspx and simple.master) it works just fine (but damn that page looks ugly!).

Does anyone know what I might be missing?

Update: I believe the reason it doesn't work is because my custom login aspx is not part of the Claims Based Web Application (because it's sitting
