Re: [lwip-users] tls server, http1.1, pipelining

[Mário Luzeiro]

Thanks Tushar,
will it be a trivial change to request http2 connection or something more 
complicated?

Can you point me any site where can I learn about it and to try establish a 
http2 negotiation?
I was trying the http2 standard webpage but I was getting to lost :)

Mario

If you are using resource constraint devices like micro controller with low 
MIPS. Then the only option is to use http2 with tls.
http1 with tls will create multiple connections. to get the web page data while 
the http2 will create single tls connections to do rx tx operations.

I managed to get a TLS server working with lwIP!

I have a webpage with html and images. It loads ok over http.
My problem is now with TLS it cannot load the images.

If I set the server using HTTP1.0 the browser will send multiple parallel
TLS connections to get the images.
So it looks this multiple connections are not supported? in lwIP/mbedTLS?

If I set the server to send a HTTP1.1 with keep-alive, the browser will keep
the connection but will send multiple READs
but why does it work (multiple readings) with regular HTTP and not over TLS?

I checked and it looks there is no HTTP option to ask client to not perform
pipelining.
