This is the primary log which keeps track of all HTTP requests made to the Platform Server. Image Rendering, if enabled, writes its access log data to the same file.
The access log is configured in server.xml.
In addition to client traffic for Image Serving ( /is/image/*) and Image Rendering ( /ir/render/*), the access log may include certain internal traffic: access to the Platform Server catalog system ( /is-catalog/*), cache sharing and error redirect requests ( /is/cache/*), access to other packages deployed to the Platform Server, such as the Scene7 Viewers ( /is-viewers/*), static traffic and static contents requests serviced by the Platform Server (e.g. /is-docs/*).
Requests with /is-catalog and /is/cache root paths should always be excluded from any client traffic analysis.
