The "robot-restrict" setting:

The VALUE of this setting is a list of GLOB patterns that match pages for which complex HTTP requests from unauthenicated clients should be disallowed. "Unauthenticated" means the user is "nobody". The recommended value for this setting is:

timelineX,diff,annotate,zip,fileage,file

The "diff" tag covers all diffing pages such as /vdiff, /fdiff, and /vpatch. The "annotate" tag also covers /blame and /praise. "zip" also covers /tarball and /sqlar. If a tag has an "X" character appended, then it only applies if query parameters are such that the page is particularly difficult to compute.

In all other case, the tag should exactly match the page name.
