Hi,
i would like to build simple HTTPD server using libevent2. It is going
to send some quite big files but i would like it to handle couple
concurrent connections. The files can be sent in chunks so I'm using
evhttp_send_reply_chunk for this. The problem is, how can I send big
files while still being able to handle new connections?
One option is to add the functionality to evhttp.
I don't have any concrete patches to post, but when I tried this a
(long) while ago, it was fairly straightforward, just building on top of
the existing bufferevent watermark functionality.
More specifically, it amounted to having evhttp_write_buffer apply a
suitable bufferevent_setwatermark (EV_WRITE lowmark) when called from
within evhttp_send_reply_chunk, setting up evcon->cb to invoke the
user's "send more data" callback from evhttp_write_cb. This worked, to
the extent that I tested it.
