#Sitecore Tip: Increase the timeout before installing .update file in UpdateInstallationWizard page.
Lately, I’ve encountered a lot of timeouts while installing an .update package in the UpdateInstallationWizard page, and I hope this post might be helpful for those developers who might ran into this kind of problem as well.
Issue: When you reached the timeout, you would see a sitecore login in the center of the page. And when you logged-in, it would repeat the installation from the start.
In web.config, increase the httpRuntime executionTimeout to 18000 (3 hours)
<httpRuntime maxRequestLength="512000" executionTimeout="18000" enableKernelOutputCache="false"
In web.config, increase the .ASXAUTH timeout to 180 minutes (3 hours), just to give more time.
<forms name=".ASPXAUTH" cookieless="UseCookies" timeout="180" />
In web.config, adjust the sessionState timeout to 180 minutes (3 hours), please don’t forget to revert it back to its default value or from its original value.
<sessionState mode="InProc" cookieless="false" timeout="180" ...
<setting name="Authentication.ClientSessionTimeout" value="180" />
Note: Please don’t forget to revert back the original value after the installation.
