weighttp (0.3-2) unstable; urgency=low
[ Jyri J. Virkki ]
* Fix header parsing to compare HTTP header field names case insensitively. This fixes the problem where responses get incorrectly marked as errors if the response header field name case doesn't happen to match to what is in the code.
[ Ben Brown ]
* Corrected Host header handling (fixes #2477)
* User-Agent header no longer needs a leading space
