Looking at the code extracts you've given I suspect something like this
is happening:

1) browser sends first request
2) server calls http_recv() which starts to send first file in reply and
stores state in the "hs" structure
3) browser sends second request
4) server calls http_recv() which starts to send second file in reply
and overwrites the state in the hs structure
5) http_sent gets called for the first request and looks at the hs
structure; it finds state relating to the second file and sends some of
that.

i.e. I think your problem is in handling overlapping requests from the
server when you haven't finished sending the first one.
