You don't. Tomcat handles that.

Hi Mark Thomas,

Thanks for response.

Need input on the below param

SETTINGS_MAX_FRAME_SIZE  :
 Windows_Update has Window Size Increment (31) ,please share the default value in Tomcat.

Please confirm the below of my assumption for the Setting parameter and Windows_Update is correct

SETTINGS_MAX_CONCURRENT_STREAMS   :  We can use  " maxConcurrentStreamExecution"
SETTINGS_MAX_HEADER_LIST_SIZE  :  maxHeaderSize
SETTINGS_INITIAL_WINDOW_SIZE   :  initialWindowSize

Correct.

Incorrect. Defaults to unlimited. Not configurable. Note that Tomcat
will apply other limits, not related to the protocol including
maxHeaderSize.

> SETTINGS_INITIAL_WINDOW_SIZE   :  initialWindowSize

Correct.

Re: HTTP/2 SETTINGS Parameters and WINDOW_UPDATE : Tomcat:9.0.11

markt
Sending a private email to an individual to try and elicit a response is
not viewed as acceptable behaviour on this list.

Speaking personally, it will not cause me to answer a question any
faster. At best, I'll answer when I'm ready. Catch me in a bad mood and
I may choose not to answer at all.

If you want replies to questions provided in specific timescales, you'll
need to find and pay for commercial support.

Given that Tomcat is open source, have you considered looking at the
source code?

RE: HTTP/2 SETTINGS Parameters and WINDOW_UPDATE : Tomcat:9.0.11

S Abirami
Hi Thomas,

Thanks for your response still now.
It helped me lot. As in earlier mail , I have partial reply .  Hence sent both user alias and individual to get the response.

I hope ,I sent in a wrong time where your mail expose your mood. I will check on the package org.apache.coyote.http2.
I hope we have payed support also. I will check  on that aspect  also.
Sorry if my individual mail troubles you.

Regards,
Abirami.S
