Hi all!

I need to catch some user-agents. Googled a lot for examples, tried a million of regexp options, and it still doesn't work:

Code:
<If "%{HTTP_USER_AGENT} == '/^.*(Google|bing|Windows|Gecko).*$/'">
Require all granted
</If>

But RE doesn't work.

Menwhile, RegExp as such works fine. And it clearly points to my wrong homebrew Apache syntax.

This is what I already tried as well:
[code]<If "%{HTTP_USER_AGENT} == '^.*(Google|bing|Windows|Gecko).*$'">
Require all granted
</If>

[code]<If "%{HTTP_USER_AGENT} == '~/^.*(Google|bing|Windows|Gecko).*$/'">
Require all granted
</If>
[/code]
And so on.

Nothing worked.

Please advise!

Try the following:

Code:
<If "%{HTTP_USER_AGENT} =~ /(Google|bing|Windows|Gecko)/i">
  Require all granted
</If>

I've removed the single quotes, also gone for regex match rather than equality, and finally requested a case insensitive match.

See https://httpd.apache.org/docs/2.4/expr.html for other syntax examples.
