TCP connection reset when 'Logout URI Include' configured.
TCP connection resets, reporting BIG-IP APM error messages. 'Logout URI Include' does not support custom query strings in logout URIs to include. For example, with a 'Logout URI Include' value of /logoff.html, if a user-agent sends a logout URI request in the form of /logoff.html?a=b, logout URI validation resets the connection and reports an error: -- Access encountered error: ERR_ARG. File: ../modules/hudfilter/access/access.c, Function: access_check_uri_type. Note: BIG-IP APM prohibits the configuration of 'Logout URI Include' from containing a query string on the BIG-IP system. For example, attempting to configure 'Logout URI Include' with a URI in the form of /logoff.html?a=b fails and displays error messages: -- Configuration error: Configured URI (/logoff.html?a=b) is not allowed to contain query parameter.
-- Access Policy with a valid 'Logout URI Include' string, e.g.: /logoff.html -- Request to 'Logout URI Include' URI from user-agent that includes a query parameter string, e.g.: /logoff.html?a=b
None
The system now ignores unsupported query parameters.
