Hi Henrik

I solved my problem....it was related to the following acl:
acl bad_word_content_type url_regex -i sesso culo culi tette nudo nuda seno seni pene cazzo cazzi teen figa streaming tvgratis

However...In order to solve this problem I was forced to disable acl per acl because increasing debug_option didn't help me; thus I would like to ask you a tips related to the log handling (I think also it could be useful for stupid people like me....)

I'll briefly try to explain:
1) visiting www.comune.milano.it the user/credential pop-up was shown to me
I tried to increase debug_option but it didn't help me because log was confused

My squid.conf is:
acl bad_word_content_type url_regex -i sesso culo culi tette nudo nuda seno seni pene cazzo cazzi teen figa streaming tvgratis
acl porn dstdomain "c:/squid/block/pornblock.txt"
acl ftpblock url_regex -i \.exe$ \.mp3$ \.asx$ \.avi$ \.mpeg$ \.qt$ \.ram$ \.rm$ \.iso$ \.wav$ \.aif$ .\wma$ .\wmv$

http_access deny Proxy_Internet_Ts !trustedsites
http_access allow enabled
http_access deny porn !Proxy_All_Open
deny_info ERR_PORN_ACCESS_DENIED porn
#http_access deny bad_word_content_type !Proxy_ftp_porn_block_yes !Proxy_All_Open (DISABLED TODAY)
deny_info ERR_PORN_ACCESS_DENIED bad_word_content_type

http_access deny msnweb !Proxy_Messengers_yes !Proxy_All_Open
http_access deny msnit !Proxy_Messengers_yes !Proxy_All_Open

http_access deny rs_deny !rs_allowed
http_access deny ftpblock !Proxy_ftp_porn_block_yes !Proxy_All_Open
http_access allow autorizzati DomainUsers
http_access deny all

Finally...the question is:
In my opinion the best and simply way to debug should be to append the name of acl in access.log as shown:

----------access.log----------
1163682256.166 125 172.16.100.95 TCP_MISS/302 370 GET http://www.comune.milano.it/ smmi\castols DIRECT/217.31.113.35 -
1163682256.885 0 172.16.100.95 TCP_DENIED/407 2012 GET http://www.comune.milano.it/webcity/portale/homepage.nsf/index.htm? - NONE/- text/html !!!ACLNAME!!!
----------access.log----------

Is it possible? I didn't find the way.

Thanks

Are you using NTLM authentication?

Could also be some embedded object in the page which was denied, such as an ad or similar.

You could try the FAQ "I set up my access controls, but they don't work!
why?"
<url:http://wiki.squid-cache.org/SquidFaq/SquidAcl#head-57ab8844e9060937c4a654e1aa7568f87cb25aef>

maybe it shows some light into the problem.
