[squid-users] squid accelerator problem (2.5.STABLE12)

Hi all,

I have a setup as follows:

[internet] -> [squid] -> [internal webserver]

the squid should work as a reverse proxy (accelerator) for the webserver.
The squid is listening on externalIP:80. The webserver is listening on
127.0.0.1:80

My squid.conf is as follows:

-- CUT --
http_port 83.221.136.66:80

httpd_accel_host 127.0.0.1
httpd_accel_port 80

cache_dir ufs /dev/shm/squid 100 16 256

httpd_accel_uses_host_header on

acl all src 0.0.0.0/0.0.0.0

http_access allow all
miss_access allow all
-- CUT --

Startup of squid seems to work fine:

The problem is that all requests to the webserver are denied:

-- CUT --
1133774372.947 0 xx.xx.xx.xx TCP_DENIED/403 1415 GET
http://my.domain.name/ - NONE/- text/html
1133774372.948 1 yy.yy.yy.yy TCP_MISS/403 1505 GET
http://my.domain.name/ - DIRECT/xx.xx.xx.xx text/html
-- CUT --

The weird thing is that it works fine if the webserver runs on port 81
instead of 80 and (eg. squid sends requests to 127.0.0.1:81 instead of
127.0.0.1:80)

What am I missing in my configuration?

Regards
