Hi!
I have a server I'd like to download hundreds of pages from, and only
get the first few kilobytes of every page to save resources on both my
and the remote end. Since the serfver doesn't support HTTP range to
use it in curl like curl_setopt($ch , CURLOPT_RANGE, "0-5000"); I
started looking around and found that using the custom write function
I might be able to do the same.
As I understand it, closing the handle and thus terminating the
transfer from within the callback function is not possible, so I'm a
bit stuck..
How could I achieve this? Could someone paste me a fewliner example?
Thanks in advance

Have you though using a HTTP HEAD request instead of a HTTP GET request?
Cheers,

As I understand it, the HTTP HEAD request would get me a response that
doesn't have the body of the file in question. The target of my file
downloads are about 20% into body of the file, so this approach
wouldn't work.
Thank you for the suggestion though! sh******@gmail. com wrote:

TCP Sockets. GET requests are not *that* difficult to implement.

Could you please show me an example of this? I'm not sure what I'm
supposed to be googling for at this point. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

My for() loop seems pretty straightforward, so not sure why only the...
