Hello development folks,

since I am currently working on a patch(set?) allowing to enable the web proxy for ORANGE
through the web interface, I stumbled across lines 3603 to 3613 in the proxy.cgi file:

> 	if ($netsettings{'BLUE_DEV'})
> 	{
> 		print FILE "delay_access 1 allow IPFire_green_network";
> 		if (!-z $acl_dst_throttle) { print FILE " for_throttled_urls"; }
> 		print FILE "\n";
> 		print FILE "delay_access 1 deny  all\n";
> 	} else {
> 		print FILE "delay_access 1 allow all";
> 		if (!-z $acl_dst_throttle) { print FILE " for_throttled_urls"; }
> 		print FILE "\n";
> 	}

This block appears odd to me, particularly due to the block in lines 3615 to 3625:

> 	if ($netsettings{'BLUE_DEV'})
> 	{
> 		print FILE "delay_access 2 deny  IPFire_ips\n";
> 		if (!-z $acl_src_unrestricted_ip)  { print FILE "delay_access 2 deny  IPFire_unrestricted_ips\n"; }
> 		if (!-z $acl_src_unrestricted_mac) { print FILE "delay_access 2 deny  IPFire_unrestricted_mac\n"; }
> 		if (($proxysettings{'AUTH_METHOD'} eq 'ncsa') && (!-z $extgrp)) { print FILE "delay_access 2 deny  for_extended_users\n"; }
> 		print FILE "delay_access 2 allow IPFire_blue_network";
> 		if (!-z $acl_dst_throttle) { print FILE " for_throttled_urls"; }
> 		print FILE "\n";
> 		print FILE "delay_access 2 deny  all\n";
> 	}

While the entire CGI is rather - um - hacky at some points, I suspect the first code block
to be related to throttling on GREEN, which is not involved into the presence or absence of
the BLUE interface. Or am I missing something here?

Thanks, and best regards,
Peter Müller

And why would that be a good idea?

It is indeed a file that has been worked on over decades. It isn’t cut from just one piece of marble, but made out of many small pieces.

However, I do not know what you are asking. What does “odd code” mean?
