Hi.
Thanks to both for your suggestions and explanations.
The version of mod_jk on that system is 1.2.18, and
I have not any of the JKOptions Forward* configured in my setup, which is just this :
JkWorkersFile /etc/apache2/workers.properties
JkLogFile /var/log/apache2/mod_jk.log
JkLogLevel debug
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
Anyway, adding
JkOptions +ForwardURICompat
works !
(which is strange, because the docs says it should be the default before 1.2.22)
Now I'll see if I can get a more recent mod_jk as a Debian package, and else I'll see if I
can make one myself, so that I can use the latest default ForwardURIProxy.
I also did not understand the reason why in the docs it says "This is .. not safe if you
are using prefix JkMount."
Anyone care to elaborate ?
I am not using "prefix JkMount" specifically, but I am using
<Location "/mir">
SetHandler jakarta-servlet
</Location>
Does this un-safeness apply in that case also ?
