The problem here is that the HTTP response seems to miss the “reason
phrase” as specified in
<http://www.w3.org/Protocols/rfc2616/rfc2616.txt>.
Or, to put it differently, it provides an empty reason phrase, which I
think is valid per the RFC, Section 6.1:
Reason-Phrase = *<TEXT, excluding CR, LF>
The problem is that (web http) strips trailing white space on the
response line, in its ‘read-line*’ procedure. Changing
‘read-response-line’ to use ‘read-line’ (which does not strip trailing
space) instead of ‘read-line*’ fixes the problem.
I believe this is the right thing to do here. Thoughts?
Thanks,
Ludo’.
