Hi,
HTTP_Request2 supports keep-alive in HTTP requests.
The question is now how to use it.
The following naive code does not use it:
<?php
$req1 = new HTTP_Request2('http://example.org/1.htm');
$res1 = $req1->send();
$req2 = new HTTP_Request2('http://example.org/1.htm');
$res2 = $req2->send();
?>
As far as I see, the keep-alive support is implemented in the adapter.
This means that I could create the adapter myself and share it:
<?php
$adapter = new HTTP_Request2_Adapter_Socket();
$req1 = new HTTP_Request2('http://example.org/1.htm');
$req1->setAdapter($adapter);
$res1 = $req1->send();
$req2 = new HTTP_Request2('http://example.org/1.htm');
$req2->setAdapter($adapter);
$res2 = $req2->send();
?>
This forces me to choose the adapter myself, which I might not want.
Another option is to re-use the request object:
<?php
$req = new HTTP_Request2('http://example.org/1.htm');
$res1 = $req->send();
$req->setURL('http://example.org/1.htm');
$res2 = $req->send();
?>
This works, but the issue I have here are headers, the request body and POST data. They are - as far as I see - not reset between requests.
Now my questions:
1. Is the observation about not-resetting headers between requests correct?
2. Did I forget some way to do keep-alive?
3. What's the best way to use keep-alive with HTTP_Request2?
