Summary: Domain pattern globbing confusion

Initial Comment:
Hello all;
The Privoxy Manual (3.0.6) states under Actions Files section 8.4.1 (the domain pattern) that the dot "." is used to unanchor the start or end of a pattern.

Thus:
.example.
matches www.example.com; or "any domain that includes '.example.'" INCLUDING the dots.

In other words, the dot "." is not a metacharacter, it's a literal dot. The ".example." above DOES NOT match "http://example.com" according to the Manual. Except it does.

I have a problem understanding why the following does NOT work:

I have a domain "http://algore.com/.  When I try to pattern match as follows:
"algore.com/...path pattern..." Notice NO dot before "algore", which should match because it's exactly what the domain is. But no joy. In the debug process, indeed it states it has "matched", and the subsequent "-block" rule has been enforced, but in practice it is not followed. Not until I rewrite as: ".algore.com/...path pattern..." does it work!

Except as I understand the manual, ".algore..." SHOULDN'T work for "http://algore.com..." because the dot "." unanchors it and as the Manual states under sec. 8.4.1, should "match any domain that contains .example.." Not: "that contains example". Note the dots.

So how am I to understand the dot globber? Is it a place-matcher, or a character-matcher or both, or neither? Help...

A would-be Privoxy fanatic,
Matthew

Thanks for the report, the manual is incorrect
and .example.com/ should match any domains with
first-level domain "com" and second-level domain
"example". For example it should match:

www.example.com
example.com
and
foo.bar.baz.example.com

but not:

another-example.com

because here the second-level domain isn't "example".

The dot in domain patterns is used as a domain
boundary marker and the dots in the real domain
are interpreted as domain boundaries as well,
not as real characters.

Can you post your exact pattern and the URL that should
be matched but isn't?

Provided the path pattern matches, the missing dot
shouldn't prevent the match in your example.
