Overpass API developpement

Hi everyone,

Thank youf or asking. I'm not an Apache expert, but I'll try my best.

When I have requested the url
http://175.33.148.57/api/interpreter
just now, I have got "504 Gateway Timeout".

I suggest the following measures:

Try the request /api/test.pl
This should produce a status page that lists all environment variables. 
If this works then it is a problem with the Overpass configuration. 
Otherwise it is most likely a problem with the Apache configuration.

Please have a look at the error log. It could be at
/var/log/apache2/error.log
or wherever the entry "ErrorLog" in your confguration file points to.
In particular, if the request leaves no traces in the log files, then it 
doesn't even arrive at the Apache server.

Another thing that interfered with Apache CGI in the past was AppArmor. 
I don't know where it has its logfles and configuration. Some distros 
also have SELinux for a similar pupose.

Otherwise I suggest you send the (by timestamp) relevant content of the 
error log and the Apache configuration file to this list. You may send 
it to me in a private mail if you don't want to appear it in the public 
archive.

As a final remark, Apache 2.2 uses

  Order allow,deny
  Allow from all

while Apache 2.4 uses for the same purpose

  AllowOverride All
  Require all granted

These settings each don't work in the respective other version.

Best regards,

Roland
