We use a loose hash to match incoming requests with recorded flows. At the
moment, this hash is over the host, port, scheme, method, path and content of
the request. Note that headers are not included here - if we do want to include
headers, we would have to do some work to normalize them to remove variations
between user agents, header order, etc. etc.
Module is in the Public Domain.
I expect to modify and extend this module, so I've imported into main library
rather than contrib. Code has been reformatted to suite our code standard,
tests have been extrated into /tests directory.
