Starlette includes support for HTTP/2 and HTTP/3 server push, making it
|
||
|
|
possible to push resources to the client to speed up page load times.
|
||
|
|
|
||
|
|
### `Request.send_push_promise`
|
||
|
|
|
||
|
|
Used to initiate a server push for a resource. If server push is not available
|
||
|
|
this method does nothing.
|
||
|
|
|
||
|
|
Signature: `send_push_promise(path)`
|
||
|
|
|
||
|
|
* `path` - A string denoting the path of the resource.
