pfsockopen problem

[Anon]

Hello,

I am writing a small php program which opens a http socket with some server, sends a head request for a particular uri.

I am fetching the content-length (if available) from the server request. And then i want to send a new request with for the same uri on the same server to get the a part of the content with the Range Header.

I don't know how exactly it is possible.

Pl. advice.

Thanks in advance.
