change ttl based on request url

[Ryan Morgan]

I'm using varnish 3. I switched it to req.http.host and simplified the regex to just "internal.my.com" and it worked perfectly. Thank you!

I believe the regex I have below should return true when the request url is “http://internal.my.com/any/thing<http://internal.my.com/any/thing>” and the 15s ttl should be set. I’ve tried just (req.url ~ “internal.my.com<http://internal.my.com/>”) as well because I read that it should match if any part of the request url. Help is appreciated! Thanks!
