in thread regex not matching special char

Thanks for the tip on YAPE::Regex::Explain.

As kennethk pointed out - reading between the lines - the key is to know that a back slashed special character will not be taken as a word character, and hence will be seen as a word boundary itself. That is why the simple \b does not work.

Armed with a definitive answer as to what is happening, a simple work around can be constructed. In my case the strings I am looking for are actual directory names. I can split on the directory separator.

Thanks again.

[ambrus]: Corion: ah, so you want a library that parses HTTP, and you want to do the IO yourself, and don't want a full AnyEvent wrapper.
[ambrus]: Corion: I think I parsed a HTTP header from a string with LWP once. You can definitely use that to create a HTTP message too. The problme is
[ambrus]: that if you do that, you'd have to find where each HTTP response ends, which is nontrivial if you want persistent connections (essential for performance if you have small requests).
[Corion]: ambrus: Yes, ideally an API that I feed the incoming data piece by piece and that I can ask "is that response done" and "what should I do next" and "please construct the appropriate redirect for me"
