Hi!
I use the wildcard *banner*. How can I exclude some URLs from this?
Thanks in advance.

That depends on what URLs you're trying to exclude.

You can only exclude content that comes after what is to be blocked. You're going to have to wait for the whitelist in 0.6.

I've had the same problem. Luckily I've found a solution. Just replace *banner* with this regular expression (modify it to your needs):

/^(?=.*?banner)((?!www.allow1.com).)((?!www.allow2.com).)*$/

That won't work.

Oh, you will probably need to precede the dots in urls with backslashes:

/^(?=.*?banner)((?!www\.allowme\.com).)*$/

/^(?=.*?banner)((?!www\.allow1\.com).)((?!www\.allow2\.com).)*$/

J.N:
Unfortunately, your 'lookbehind' phrase isn't really anchored to the pattern-start. The first url, below, should be blocked, but isn't:

/^(?=.*?banner)((?!www\.allow1\.com).)((?!www\.allow2\.com).)*$/
"www.allow3.com/banner?redir=www.allow2.com"
-> no-match
"www.allow3.com/banner"
-> match

Still, it was a nice idea. Lookbehind has been discussed here, before.
