> remove_session_route causes an infinite loop when parsing jsessionid out of URLs.  The stack of the looping thread is:
> {code}
> #0  0x00007f4cf2b66e45 in remove_session_route () from /etc/httpd/modules/mod_proxy_cluster.so
> #1  0x00007f4cf2b68ad9 in ?? () from /etc/httpd/modules/mod_proxy_cluster.so
> #2  0x00007f4cf2f7d116 in proxy_run_pre_request () from /etc/httpd/modules/mod_proxy.so
> #3  0x00007f4cf2f84186 in ap_proxy_pre_request () from /etc/httpd/modules/mod_proxy.so
> #4  0x00007f4cf2f813c2 in ?? () from /etc/httpd/modules/mod_proxy.so
> #5  0x00007f4cf776df70 in ap_run_handler ()
> #6  0x00007f4cf777180e in ap_invoke_handler ()
> #7  0x00007f4cf777cfd0 in ap_process_request ()
> #8  0x00007f4cf7779d48 in ?? ()
> #9  0x00007f4cf7775a58 in ap_run_process_connection ()
> #10 0x00007f4cf7781fa7 in ?? ()
> #11 0x00007f4cf77822ca in ?? ()
> #12 0x00007f4cf7782f4c in ap_mpm_run ()
> #13 0x00007f4cf7759ab5 in main ()
> {code}
> That is looping here:
> {code:title=mod_proxy_cluster.c}
>                 while (*path !='&' || *path !='\0')
>                     path++;
> {code}
> "*path !='&' || *path !='\0'" is a tautology so the while never ends.  It should be an &&  instead of ||.
