Hi,

Recent chrome  [Mac - Sierra : Versio=
n  55.0.2883.87 (64-bit) ] we are seeing issues in http2 sites.=20


Initially we have seen problem with http2 table header size limit error and=
 to fix this, we have upgraded tomcat 8.5.4 to 8.5.9 where tomcat has incre=
ased the header limit from 16K to 64K.=20


Now with latest tomcat 8.5.9 we are seeing  ERR_SPDY_COMPRESSION_ERROR whil=
e loading dojo libraries.

Tried couple of steps (flush SPDY sokets e=
tc) based on google search on this issue but nothing worked..

Initial content =
is downloaded (other JS files etc) but on some dojo libraries alone, we are=
 this issue which make application home page load fails.


Firefox works!


We are having latest tomcat 8.5.9 already. Not sure where else problem now.=
 We have not enabled any compression server side.


https://bugs.chromium.org/p/chromium/issues/detail?id=3D673315=
 (Chrome bugs i have raised)

    My guess is that the bug is in Tomc=
at, in that it does not send an HPACK dynamic table size update (so the dyn=
amic table should be the default 4 kB) but uses a 64 kB dynamic table.      As soon as it references entries that are in fact already emitted, tha=
t's a compression error.  
    See https://www.ietf.org/mail-archive/web/httpbisa/current/msg2786=
7.html for a discussion on how to interpret the specs.

Acco= rding to the chrome bug notes problem is with tome dynamic table size 64k. = I don't know how to confirm this is as tomcat issue as well. 

Can somebody help here to trace the problem?
