Re: cURL in PERL HELP.

I found some more information,  the url contains the date and time stamp the file was created.

20061031033112. 

I will always know the date but not the time stamp of the file I am looking for. Any suggestions?  thanks for all of your help?

Thanks

Yes. If they send different data in the POST (as the command lines differ
there), aren't they supposed to return different results then? And if you
intend to send the same data, why not use --trace-ascii in both commands and
just compare the traces afterwards to see how they differ?

Multiple HTTP GETs in one TCP message

Hello,
I'm a newb.
I would like use cURL to send more than one HTTP GET inside a single TCP message, is this possible with cURL?

A TCP connection is a stream by definition, so what is a "TCP message" ?

Is this a pipeline question??

Yes. Is it possible with current cURL syntax?

Yes. Is it possible to do HTTP pipelining with current cURL syntax?

Doesn't this happen automatically already?

% curl -v http://localhost/A http://localhost/B 2>&1 | grep "^\*"
* About to connect() to localhost port 80
*   Trying ::1... connected
* Connected to localhost (::1) port 80
* Re-using existing connection! (#0) with host localhost
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* Connected to localhost (::1) port 80
* Closing connection #0

To remove confusion:

There is no such thing as a "TCP message". There is such a thing
as an IP packet, but you don't really care how many IP packets your
TCP stream requires (at least 5 for proper connections ;-)).

What you want to do is to reuse connections. cURL already does this
(see above).

Cheers,
  Peter

No. curl re-uses the connection if it can, but the curl tool does not use 
pipelining. The most recent libcurl supports HTTP pipelining but it would take 
some effort to make the command line tool take advantage from that.
