webforms - asp.net: __doPostBack not rendered sometime -


We got weird error in the past days ___ Doe postback is undefined.

We are building a very advanced website, but do not use postback. A place where the postback used is ASP.NET login state control.

It is investigative, sometimes it is presented, sometimes it is not. For IE, Chrome works mostly well, but Firefox has a much higher chance of not having dot-backback in the page source.

Any thoughts?

PS: Apart from this, only error occurs on the live environment, which is called Windows 2003 & amp; IIS 5.0, dotnet framework is 3.5

Could it be because I am using the output cache at the page level?

Yes, this output may be about the cache, exit it and try again Please < / P>
