ASP.Net pages returning blank page on postback

Posted on 2014-07-18

Several of the webpages in my asp.net web application have started returning a blank page after postback. Either it happens when clicking a button to run a procedure (save), or by selecting a value from a dropdown list. This is new behavior. The only change to code that has happened lately is implementing PKI. It does not happen all of the time but it happens often enough that users are really complaining. One avenue I thought of is sessions. I noticed on one page that if I work thorough it and submit, it seems to work. If I step away or do something else for just a few minutes, when I come back and make a change to the form like select something from the dropdown list, I get the blank page. I've asked this question here before but have not gotten any responses. I've also asked several developers I know but still no go. Any help is appreciated.

when you say you've implemented PKI infastructure and it broke your webpage, could you elaborate on what you mean as PKI in itself doesn't affect IIS or the operation of websites.

The website has been up and running well for about 2 years now. I had to implement PKI on it this month. It's been PKI enabled for almost 2 weeks now. This behavior started shortly after the implementation. I have a function within the master page that takes in certificate information for each user (serial #, date of expiration) which is put into the user table and used for validation so users will no longer have to use a username and password. I'm not 100% sure it's because of PKI, but it is the only code change I've made recently. When it happens, if you refresh the page the page comes back but the changes you just made are gone and you have to start over.

Found it finally: http://www.experts-exchange.com/Networking/Protocols/SSL/Q_24461827.html

It turns out that we needed to issue the following 2 statements from
the c:\inetpub\adminscripts directory to solve the problem:

cscript adsutil.vbs set w3svc/site#/uploadreadaheadsize 200000

and set the SSLAlwaysNegoClientCert value by issuing the following
command:

cscript adsutil.vbs set w3svc/site#/SSLAlwaysNegoClientCert true

where site# is the identifier number associated with the website.
