multiple http post operations

Anon

I want to use http post (1.1) to set values into two forms (web designers.. argh). IS it possible two use multiple post operations in the same header ?

I have used a class that works fine for singe POST operations. However the second form is dependent on input in the first form (slot and port for a given interface).

Any hints on where to find http related info ?

I kind of suspect that there'd be problems with multiple Location: targets in an http header (whose response do you use?).

In a situation where I have to deliver a form's contents to multiple targets (http or whatever), I usually have the server handle the POSTS itself. A script to sort out who gets what details, build up a POST request for each target, and then fire them off one after the other.

The script can then take up each response, compile the relevant bits, and serve them back up as the response to the original form submission.

I use cURL myself, 'cos it's already installed and builds the request for you, but you can do it by hand with fsockopen and other file-handling functions.

That's just what I do; there may be more cunning methods and I may be wrong about http!

Thanx for your hint on Curl.

So to post variables to different forms, I guess they would have to be in the same curl session, like :

Or is it totally illegal to do multiple posting in a curl session? I have not tried this code, only clipped from the manual and made som naive changes :

$ch = curl_init();

curl_setopt($ch,
CURLOPT_URL,"http://www.mysite.com/tester.phtml");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
"postvar1=value1&postvar2=value2&postvar3=value3");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
"postvar4=value4&postvar5=value5&postvar6=value6");

curl_exec ($ch);

curl_close ($ch);

Could this work? (and why / why not if you have the time to explain..)

I haven't tried using the sam cURL session to send multiple requests - feel free to experiment.

My idle guess is that any options set from the first execution would still be set in the second one, unless they're overriden by further curl_setopt()s. IMHO it would be cleaner to keep them as separate sessions (with distinct handles to identify which session is handling which submission).

$ch1=curl_init("http://www.getsformone.com/");
$ch2=curl_init("http://www.getsformtwo.com/");

....

curl_exec($ch1);
curl_exec($ch2);
curl_close($ch1);
curl_close($ch2);

I tried using two separate posts- nogo.

It seems I somehow needs the info from the first post operation to fulfill the next. I guess this info is lost when the http session is over.

I did not succeed with using multiple http post operations.

I need to contact the vendor for more information on the web interface. Thanks for now, thoug, Hayley.

I let you know how things are developing.
