I have a ASP application. On click of a particular link, some VB scripts are executed and an ASP page is to be shown, but instead I get a screen that says:

Information Not Available.
The requested URL was rejected. Please consult with your administrator.
Your support ID is: XXXXXXXXXXXXXXXXXXXXXX"

The IIS and event viewer logs do not show any error message.

This happens only for some users, but works fine for other users.

What are the possible causes for this error ?

Your http is being blocked by a firewall from F5 Networks called Application Security Manager (ASM). It produces messages like:

Please consult with your administrator.
Your support ID is: xxxxxxxxxxxx

So your application is passing some data that for some reason ASM detects as a threat. Give the support id to you network engineer to learn the specific reason.
