[squid-users] Regex difficulties

[Balázs Szabados]

Hi Amos,

I tried troubleshooting you've mentioned. I just enabled one file
containing regexes.
I've measured it:
root at OpenWrt:~# wc -c /etc/squid/blacklists/regex_allow
1636 /etc/squid/blacklists/regex_allow

Since the whole file is 1636 bytes, I assume ever line of regexes is in
must be smaller than that.
Starting up squid I'm getting these:

2015/05/04 23:17:44| aclParseRegexList: Invalid regular expression
'(.*(acoon\.de|openacoon\.de|omgili\.com|youtube\.com|slug\.ch|\/search\?|mister-wong\.de|mister-wong\.com|abacho\.|seekport\.|flickr\.com|altavista|ask\..com|answers\.com|clusty\.com|exalead\.com|metacrawler|dogpile|lycos|google|yahoo|dmoz|search\.|wikise':
Unmatched ( or \(

I've created a file with just that part in the error message, and it seems
to be 256 bytes (wc -c again).
Isn't that possible, that this is the limit, you've mentioned?

Thanks,
Balazs
