You can enable and disable a variety of protocols in httpd.conf, using the SpdyEnabled directive.
Example

<IfModule LiteSpeed>
SpdyEnabled off
</IfModule>
Example
Enable HTTP protocols and disable everything else
<IfModule LiteSpeed>
SpdyEnabled http2 http3
</IfModule>
HTTP protocols are enabled by default, while SPDY protols are disabled by default.
| Parameter | Function | Default Value |
|---|---|---|
spdy2 | Enable SPDY/2 | Disabled |
spdy3 | Enable SPDY/3 | Disabled |
http2 | Enable HTTP/2 | Enabled |
http3 | Enable HTTP/3 | Enabled |
off | Disable all protocols |
Tip
When you use this directive to explicitly enable one or more protocols, anything not selected will be disabled. For example, SpdyEnabled http2 will enable HTTP/2, while SPDY/2, SPDY/3 and HTTP/3 will be disabled. Be careful not to inadvertantly disable a protocol you wanted to use!
