HTTP/2 Over Cleartext TCP doesn't work ?

[webmastergreg]

Hello,
as now http/2 is ok on my server with LS5.0 build 14, I would like to have it to all.

But http/2 is only active over https, so I've set the option in configuration :
Enable HTTP/2 Over Cleartext TCP : YES

But it make no change, http/2 is only with https.

it's also related to this:

can't bypass browser's limitations ?

any idea ?

Thanks

No major browser support H2C, it only works with special clients at this moment. It is not a sever side issue.

hi
ok
but for FF 38.0.1 if under https I already get this response (in bold):

Accept-Ranges bytes
Content-Encoding gzip
Content-Type text/html; charset=utf-8

Pragma no-cache
Server LiteSpeed
Vary Accept-Encoding,User-Agent,User-Agent
X-Content-Encoded-By PHP
X-Firefox-Spdy h2

so perhaps it at least detects it, but I think it works already.
Same for chrome, protocol seems ok under https:

Firefox and chrome will use HTTP/2 by default for https connection.

 

[webmastergreg]

yes
we agree, and so at this time https is just mandatory, as the link said it in my previous post.
At the start, I just wondering if the option in the litespeed configuration could bypass this restriction, but it seems that not.

Anyway thanks again mistwang
