Hi All,

we are upgrading the asp.net 2.0 web application to asp.net 4.0. we are using form authentication.

<authentication mode="Forms">
	<forms name=".ASPXAUTH" protection="All" timeout="30"  loginUrl="user/login.aspx"></forms>

	<deny users="?"/>

<location path="default.aspx">
			<allow users="?"/>


the site default page is default.aspx

in version 2.0, working fine with form authentication.

after the upgradion

whenever call website .com/" mce_href="http://www..com/">http://www.<domainname>.com, it is redirected to login page

.com/user/login.aspx?ReturnUrl=%2f" mce_href="http://www..com/user/login.aspx?ReturnUrl=%2f">http://www.<domainname>.com/user/login.aspx?ReturnUrl=%2f 

if we call .com/default.aspx" mce_href="http://www..com/default.aspx">http://www.<domainname>.com/default.aspx, it is working fine

Commerce with ASP.NET: Leverage the Authentication and Form Validation Features of ASP.NET to Bolste


If you're planning to build an e-commerce site, you'll be pleased to see that ASP.NET makes it easier than ever. Existing controls can be used and extended to add a great deal more functionality than you might expect. In this article, forms-based authentication is used to verify the identity of users and make certain areas of the site, such as the check-out page, inaccessible to unauthorized users. The power and flexibility of validation controls are demonstrated using the CustomValidator control to connect to a Web Service that verifies addresses. A shopping cart is then implemented in ASP.NET using the DataGrid, and finally, credit card authorization and billing are performed.

POST from html form viewstate problem

<p> Hi all, I have a website where people need to pay for a specific download (.pdf file). After they payed they get the download(A). My payment-provider can do a HTML-Postback to the site i want, for each succesfull payment. So the idea is that if someone payed, they do a postback to my server with a couple of parameters, so i can know that that specific email address has payed, and they get the download. I tested localy with a .html file on my desktop to postback a set of parameters to my local asp.net website. But in ONLY works if i include the __VIEWSTATE in my html file. And i cant get rid of the viewstate in my HTML of the aspx page. >test.html: <html><head></head><body> <h1>Dit is een test</h1> <form id="form1" action="http://localhost:25659/WebForm1.aspx" method="POST"> <input id="Button1" type="submit" value="submit!"/> 'IT ONLY WORKS IF I INCLUDE THE NEXT LINE: <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUKMjA0OTM4MTAwNGRk" /> </form></body></html> Has anybody an idea to acomplish my goal? Maybe i can get some info about the postback in my global.asax? or create a HttpHandler for .html files? Anyone?   Thanks in advance, Vincent   </p>

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
