Web Interface Delay Experienced by First User of the Day

When connecting to the Web Interface, there can be a delay before the first page appears. After restarting IIS, or rebooting the Web Interface server, it takes up to 1 minute to load the Welcome page for the first user. If simulation happens during this period, then it will capture and alert administrators to this delay every day, unnecessarily bothering them with an issue, that in fact does not exist. If this is to be avoided, then its best that you ensure that this delay does not occur. For that, do the following:

  1. This issue is caused by a CRL check sent to Verisign. If the Web Interface server cannot access the internet, the CRL check fails and times out. To avoid this therefore, first determine the ASP.net version in IIS that is in use with the Web Interface site. Then, open the ASPNET.CONFIG file that corresponds to that version from the C:\WINDOWS\Microsoft.NET\Framework\<.Net_framework_version> folder.

  2. Add the following lines to your ASPNET.CONFIG or APP.CONFIG file:

    <?xml version="1.0" encoding="utf-8"?>

    <configuration>

    <runtime>

    <generatePublisherEvidence enabled="false"/>

    </runtime>

    </configuration>

  3. Finally, save the file.
