I finally got a working apache2+mod_perl working in my $HOME dir (I
could not find the core files of the RedHat httpd, problems with uid
permission i guess)
So here are the backtraces.
I included two backtraces :
- the first one is for the crash with $r->send_http_header()
- the second one is for the crash with $r->print() when I remove the
send_http_header() statement
The config in httpd.conf :
# mod_perl
LoadModule perl_module modules/mod_perl.so
PerlModule Apache2
PerlTransHandler Apache::SegFault
# proxy
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
ProxyRequests On
<Proxy *>
Order deny,allow
Deny from all
Allow from localhost
</Proxy>
Then I issue a simple request with :
echo -ne "GET http://perl.apache.org HTTP/1.0\n\n" | nc localhost 8081
