[users@httpd] Re: Apache 2.4: Mod Cache: authorization required
Hello,
Ok I figured out how to allow caching for authenticated urls: adding
"Cache-Control" header with public option do the trick.
Now I still have the problem that the cache key is built upon the url
BEFORE the rewrite occurs.
Is it possible to change this behavior ?
I tried with
AddOutputFilterByType REWRITE;CACHE text/html
But rewrite is not a filter (or I don't have the appropriate name).
Thanks,
Nicolas

Hi,
> Isnt it what CacheStorePrivate is for?
I tried with this option only, it doesn't work. Seems correct as the
docs says:
"Ordinarily, responses with Cache-Control: private header values will
not be stored in the cache. The |CacheStorePrivate| directive allows
this behavior to be overridden. |CacheStorePrivate| On tells the server
to attempt to cache the resource even if it contains private header
values. Resources requiring authorization will /never/ be cached."
Notice the " Resources requiring authorization will /never/ be cached."
Anyway it works with Cache-Control: public.
I also found a solution for my other problem: cache key computed before
rewrite. Adding a [PT] to the rewrite rule do the trick !
Thanks !
