Case Insensitive Regular Expressions

Hello,

It doesn't appear that VCL supports case insensitive regular
expressions. Is this true?

I have tried all the methods that I am aware of to signify case
insensitivity, and none seem to work.

Any help would be appreciated.

Thanks.

Yes because I didn't think of that.

Hmm... won't this potentially mess up support for multiple hostnames/
backends? Using the example from the man page:

if (req.http.host ~ "^(www.)?example.com$") {
set req.backend = www;
}

I assumed this would match example.com and Example.com. Is this not
the case?

Now it is, I just changed regexp's to be case insensitive.
