Hi.
One recommendation beforehand: If you can live with the memory
footprint, use mod_perl. It gives you full access to the apache API and
it is much easier to handle.

If str was \0 terminated, you would not need a length. In the above
case, you better move the bucket you just read.

You need to punch a \0 into str, the you can use it as head.
You also need to handle the case that <head> is broken into 2 parts in 2
buckets.
