When running a Web Agent protecting an application, the browser gets the following errors when accessing the URL '/myURI/MyServlet;variable=value':

   "URL contains invalid characters. Exiting with HTTP 500 server error '00-0002'."

In the ACO, the following parameters are defined:


When removing the semicolon character from the BadQueryChars then the browser can access the URL above, but as there is no query string in the URL, why it is complaining about BadQueryChars, there's even no semicolon defined in the BadUrlChars parameter?




Web Agent R12.52 SP1 CR05




As per documentation (1)(2), BadQueryChars "specifies characters that the Web Agent prohibits in the query string portion (following the '?') in a URL." When the URL does not contain a '?' character, the Agent is checking the whole URL for BadQueryChars

This issue is fixed in Web Agent 12.52SP1CR09 (3).




Upgrade to version 12.52SP1CR09 to fix this issue.
