Subject: Implement windowsize support more in line with specs.
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=a2addaa126ca0dd7b19ab60df77ae1532746761b;p=horde.git

Implement windowsize support more in line with specs.

Per MS specs, windowsize should default to 100 if not specified by client,
and should default to 512 (the max) if the value specified is
out of range.
