Just to be sure I understand your problem correctly: the link checker  
is not using your network's proxy and therrefore some addresses don't  
resolve, or does it use the proxy and have issues resulting to that?

If the former, I suspect that:
- enabling mod_env in your apache server (supposing that's what you  
are using)
- using apache's SetEnv as follows in the configuration nearby that  
of the link checker SetEnv http_proxy http://username:password@your- 
proxy-host:port/

There should be nothing to add to the link checker code itself, the  
release 4.2.1 already takes into account the proxy environment  
variables.

(for reference, that's http://lists.w3.org/Archives/Public/www-

yes, that looks correct, minus the patch to the checklink script,  
which is not necessary any more.

Could you give details how it "didn't work". Could you try modifying  
your server configuration to set up the http_proxy environment  
variable, restart apache, and see if it works better?

Thanks,
