# Content server: Use internal redirect for single item categories
# Content server: Fix single item categories not working with reverse
# proxy setup. Fixes #1238987 [Calibre behind apache server sometimes returns 'localhost' URLs](https://bugs.launchpad.net/calibre/+bug/1238987)
# 
# Single item categories were using HTTP 303 redirects which are resolved to
# http://localhost:8080 absolute URLs by cherrpy (since cherrypy has no
# knowledge of whatever server the apache process is exposed as). SO
# instead we use an internal redirect, which does not suffer from this
# issue. It does mean that bookmarking the URL wil have unexpected
# side-effects if the number of items in the catefory ever increases to
# more than one.
