Maybe you can try my patch, https://github.com/kn007/patch/blob/master/nginx.patch

[centminmod]

have you tried with nginx 1.3.10 master branch you patch as huge amount of changes in src/http/v2/ngx_http_v2_filter_module.c at https://github.com/nginx/nginx/blob/master/src/http/v2/ngx_http_v2_filter_module.c

[kn007]

Oh, sorry. My mistake. I do not test it on 1.13.10.

[kn007]

@centminmod Fix. https://github.com/kn007/patch/blob/master/nginx.patch

[centminmod]

Thanks @kn007 seems your patch is 3 in one for

Add SPDY Support.
Add HTTP2 HPACK Encoding Support.
Add Dynamic TLS Record support.

Do you have HTTP HPACK patch by itself ?

[kn007]

@centminmod I'm off work now. I'll make patch for you when I get home.

[kn007]

https://github.com/kn007/patch/blob/master/nginx__1.13.10_http2_hpack.patch

[centminmod]

Thanks @kn007 it patched perfectly in 1.13.10. Very much appreciate your help with this !

[kn007]

You are welcome.

[PikachuEXE]

I test with https://http2.domain.com with h2load but space saving is 0% Is it reverted?

I test the patch with my own website but IE11 in win10 does not like it :P

[centminmod]

@PikachuEXE what's happening in IE11 ?

[PikachuEXE]

It won't load after first request

[kevin25]

I tested on IE 11 Windows 7 and worked for me.

[PikachuEXE]

What website do you use for testing?

[PikachuEXE]

I test the patch with our own website with BrowserStack IE11 on Win7 again The status code is HTTP/1.0 503 Connect failed

edit: this error is caused by incorrect Nginx config, let me post the actual error later

[PikachuEXE]

OK this is our testing website: https://staging.spacious.hk/en/hong-kong/for-sale Currently using Nginx with the HPACK patch applied

IE11 on Win7 on BrowserStack sometimes crashes, which is why I am not sure if it's working for IE 11 or not

[kevin25]

Is it?

[kn007]

Using win7 system with IE 11, it was working fine.

[PikachuEXE]

Thanks guys :) Maybe I should try to create a windows VM for testing instead ~_~

Oh 1.13.11 is out, need to test again :3

[PikachuEXE]

Tested with Virtual box VM with IE11 on win 7 The patch works fine for Nginx 1.13.11

Any idea if it works with Nginx 1.14.0?

[kn007]

@kevin25 Even using my patch? It seems that these hunk errors are not caused by my patch.

You could using this one: https://github.com/kn007/patch/blob/master/nginx__1.13.10_http2_hpack.patch

Pls delete the old files and re-extract the nginx-1.14.0.tar.gz, then patch the patch to try it again.

[kevin25]

Yes, i did. This one seems to work. I'll test it. Thank you. Cloudflare team doesn't support this anymore?

[anotherjin]

Cloudflare is using their own server, see their blog

[PikachuEXE]

Cloudflare open-source the patch but don't really maintain for every Nginx version

[kevin25]

https://github.com/kn007/patch/blob/master/nginx__1.13.10_http2_hpack.patch

I got 404 error
