Hi,
I have some problems with mod_proxy_html on Solaris.
On Solaris 9 (Apache 2.2.4 and Apache 2.0.55, libxml2-2.6.30) , I've
encountered the following problem with mod_proxy_html. I have
downloaded, built and installed the mod_proxy_html release ( it seems to
be released 2007-07-31). It should contain a bug fix against segfaults
(2007-06-17) but apparently I have run in to this anyway.
I also reterieved the latest version (2007-10-04) from svn , from the
log it says :
"Refuse to run (and segfault) with no links configured and nothing to
do"
I don't know if the latest svn-version could address my problem nor the
status of the svn-version , it is propably the developer version and I
should rely on the official release (2007-07-31).
I have tried to debug this but without success. Truss gives me nothing
to go on and the logs aren't very helpful. But it seems consistent
enough. Fortunately I am not forced to use mod_proxy_html, but I would
like to clean up my build if possible.
Regards,
Anders
