Description:
In the Webagent guide:
OverlookSessionForUrls
Specifies whether the Web Agent compares the URLs from all HTTP requests against the URLs listed in this parameter. If a match occurs, the Web Agent does not create or update an SMSESSION cookie. Also, cookie providers (if configured) are not updated for that request.
Default: No default
Example: Use a relative URL, such as /MyDocuments/index.html. Do not use an absolute URL (http://fqdn.host/MyDocuments/index.html).
Solution:
You can use a multi value parameter but this parameter does not accept wildcard. You have to define the complete URL.
