Re: [lwip-users] How to send a large dynamic generated http page?

Hi bill:

The httpd_raw demo you mentioned is httpserver_raw application in lwIP-contrib, 
right ?
In fact, more web server is programmed by socket, not row api ..

It can be done because I've sent up to 800k files using the original
(non-SSI) httpd and note that I was basing this on the httpd_raw (sp?) demo.
Regardless of the file size the tcp_sent callback is used to continue to
send until the file end is reached.  I would expect 10k, 100k or 1MB to be
identical in the handling.
