Access Gateway allows you to log HTTP transactions. You can log what happens with an HTTP request and response during certain times:
Between the browser and Access Gateway
Between Access Gateway and the back-end web server
You select fields from the HTTP header of a request and these fields are logged. You can then use these logged transactions to bill customers for web services or to troubleshoot whether a request is refused because the browser did not ’send the required information or because Access Gateway did not’ send the web server the required information.
This type of logging conforms to the W3C specification for proxy server logging in the common and extended log formats. This type of logging provides no information about the exchanges between Access Gateway and Identity Server. If you need to discover whether Access Gateway is obtaining the correct information from Identity Server for an Identity Injection or Form Fill policy, you need to turn on component logging. See Section 23.3.1, Configuring Logging for Identity Server.
For HTTP transaction logging, see Configuring Logging for a Proxy Service.
