This is meant as a bugfix release for CVE-2023-39120

• fix path traversal security issue
• add session_limit_block feature The session_limit_block is similiar to session_timeout_block, but instead of limiting the time, it limits the traffic. The session_limit_block allows to limit a user to a certain amount of traffic before the user will be blocked from applying again.
• add session_timeout_block feature The session_timeout_block config allows end and block a session after a certain timeout. E.g. allows to limit a user to have internet connectivity for 20 minutes and not allowing to apply again.
• Introduce variable gw_http_name/port gw_http_name holds the http hostname and port in the correct representation to work with it. Saves sprintf calls for every connection.
