LoadRunner 11.5 Fix Running TruClient AJAX IE Over A Firewall

One of our customers experienced issues when trying to run TruClient IE over a firewall using the LoadRunner MI Listener component. To narrow the issue down, they tried running other scripts based on different protocols, which worked fine. It was specific to the TruClient protocol. The TruClient script would time out after several minutes. The only error was “initialization failed: reason – timeout”.  To correct the issue, they implemented the following steps:

  1. Modify <LG>\dat\mdrv\mdrv_webIE.datfile. Add the following lines:
    SecurityRequirementsFiles=webIE.asl
    SecurityMode=On
  2. Modify <LG>\dat\mdrv\mdrv_webIENDP.datfile. Add the following lines:
    SecurityRequirementsFiles=webIE.asl
    SecurityMode=On
  3.  Create a copy of <LG>\merc_asl\web2ui.asl file. Rename it to “webIE.asl“.

Hopefully this fix will help someone else who is experiencing the same issue. This should work for both Performance Center and LoadRunner.
