data scrapping problem

Hi,
I have problem when scrapping data with curl
once I scrape page using form submit,
I receive data and everything is ok.
but when I change in form fields and resubmit, I receive same previous page.
however I am using new instance for curl.
I had some useful workaround that
I wrote two scripts : 1.php that submit form with data1
and 2.php that submit form with data2.
and at the end of 1.php I redirect to 2.php
so once I execute 1.php I got the expected results. from both 1.php and 2.php.

any idea what is going on??
Regards

When you say that you are using a new instance for curl, do you mean that you are doing a curl_init() before your second call? If not, that could be your problem.

There isn't much to go wrong. I'm sure you know the sequence:

(1) curl_init()

followed by setting needed options...

(2) curl_setopt()

and finally...

(3) curl_exec()

Another possibility -- are you setting CURLOPT_URL and CURLOPT_POST correctly in your second call to curl_exec()?

It's gotta be something simple, but sometimes the obvious ones are the toughest.
