[squid-users] squid 7.1 , url_rewrite_program does not work

[Matthias Fischer]

Hi,

I have a similar problem here after upgrading from squid 6.14 to 7.2 for
testing purposes.

'squid -k parse' shows no errors, the same config seems to start without
any errors. But redirecting produces errors. Looking in 'cache_log' I found:

***SNIP***
...
2025/10/18 01:07:34 kid1| ERROR: URL-rewrite produces invalid request:
CONNECT
http://[ROUTER_IP_DELETED]:81/redirect.cgi?category=custom_advertising&url=content-loader.com:443&ip=[HOST_IP_DELETED]
HTTP/1.1
current master transaction: master53

current master transaction: master53
...
***SNAP***

This is *v7.2*(!) - which works a bit better then v7.1. Redirecting in
v7.1 wasn't working at all...

So I have the same question. Does 'anyone' has an idea what is happening
here and how to solve it?

Thanks in advance!
