Subject Alias/Redirect incompatibility
Date Mon, 07 Aug 1995 17:22:00 GMT
Apache 0.8.7 (and 0.8.8) processes Aliases before Redirects, whereas
apache 0.6 and NCSA 1.3 process Redirects before Aliases.

Not only is this bahaviour incompatible, I would argue that the 0.8 is
wrong and 0.6 is right. Otherwise it is impossible to redirect documents
which would otherwise be processed by an Alias directive; one would
only be able to redirect documents that would map on to the main
document_root tree.

A patch follows.

This should be mentioned in the 0.8.8 release notes.

 David.
