vmod_h23
Module to control the built-in http2 transport
Usage
import h2 [as name] [from "path"] BOOL is() DURATION rapid_reset([DURATION threshold]) INT rapid_reset_limit([INT number]) DURATION rapid_reset_period([DURATION duration]) REAL rapid_reset_budget()
Overview
This VMOD contains functions to control the HTTP2 transport built into Vinyl Cache.
BOOL is()
Restricted to: client.
Returns true when called on a session handled by the built-in HTTP2 transport.
DURATION rapid_reset([DURATION threshold])
Restricted to: client.
Get and optionally set the h2_rapid_reset parameter (See vinyld(1)) for this HTTP2 session only.
Returns -1 when used outside the HTTP2 transport. Otherwise returns the previous value.
If the call leads to a change in the rate limit parameters, the current budget as retuned by h2.rapid_reset_budget() is reset.
INT rapid_reset_limit([INT number])
Restricted to: client.
Get and optionally set the h2_rapid_reset_limit parameter (See vinyld(1)) for this HTTP2 session only.
Returns -1 when used outside the HTTP2 transport. Otherwise returns the previous value.
If the call leads to a change in the rate limit parameters, the current budget as retuned by h2.rapid_reset_budget() is reset.
DURATION rapid_reset_period([DURATION duration])
Restricted to: client.
Get and optionally set the h2_rapid_reset_period parameter (See vinyld(1)) for this HTTP2 session only.
Returns -1 when used outside the HTTP2 transport. Otherwise returns the previous value.
If the call leads to a change in the rate limit parameters, the current budget as retuned by h2.rapid_reset_budget() is reset.
REAL rapid_reset_budget()
Restricted to: client.
Return how many RST frames classified as "rapid" the client is still allowed to send before the session is going to be closed.
