Subject Re: 2.0.28 and mod_jk
Date Fri, 09 Nov 2001 13:24:00 GMT
My guess (and it is just a guess) is that mod_jk has not been modified to accomodate the
new map_to_storage hook.  If jk is still using the translate phase trick of nulling out
r->filename to circumvent the directory_walk, you will almost certainly get a segfault.

If this is the case, then mod_jk's translate phase hook needs to become a map_to_storage
hook, and the code that nulls out r->filename needs to be removed.
