Problem

Recently the webserver was upgraded apache 1.3.29. Ever since I am having intermittent problems submitting post data via a web form. Displaying data works fine.

The browser says the "page can not be displayed". It also says a dns error at the bottom of the page.

I can ping the site quite fine. Any subsequent gets will work fine as well.

The research seem to indicate issues with a specific fix of the ie browser not able to handle keep alive settings well.

The browser recommendation is to turn of the keep alive or increase the time out on the keep alive.

Where is the ie keepalivetimeout kept?

HKEY_CURRENT_USER\
Software\
Microsoft\
Windows\
CurrentVersion\
Internet Settings

From the Edit menu, select New, DWORD Value.

Enter the name KeepAliveTimeout, then press Enter.

Double-click the new value, set it to the number of milliseconds in the new timeout, then click OK.

Restart the computer for the changes to take effect.

The default value for keepalivetimeout for ie

This seems to be 60 secs or 1 minute

I have increased timeout on apache to 120 secs

The problem is still there. Not sure what else to try at this point. The problem is intermittent. Sometime it occurs very frequently. And sometimes once in a while. It is definitely happening for sure.
