The present disclosure provides solutions for an enterprise providing services to a variety of clients to enable the client to use the resources provided by the enterprise by modifying URLs received and the URLs from the responses from the servers to the client's requests before forwarding the requests and the responses to the intended destinations. An intermediary may identify an access profile for a clients' request to access a server via a clientless SSL VPN session. The intermediary may detect one or more URLs in content served by the server in response to the request using one or more regular expressions of the access profile. The intermediary may rewrite or modify, responsive to detecting, the one or more detected URLs in accordance with a URL transformation specified by one or more rewrite policies of the access profile. The response with modified URLs may be forwarded to the client.

The present disclosure is directed towards tracking application layer flow via a multi-connection intermediary. Transaction level or application layer information may be tracked via the intermediary, including one or more of: (i) the request method; (ii) response codes; (iii) URLs; (iv) HTTP cookies; (v) RTT of both ends of the transaction in a quad flow arrangement; (vi) server time to provide first byte of a communication; (vii) server time to provide the last byte of a communication; (viii) flow flags; or any other type and form of transaction level data may be captured, exported, and analyzed. The application layer flow or transaction level information may be provided in an IPFIX-compliant data record. This may be done to provide template-based data record definition, as well as providing data on an application or transaction level of granularity.
