Best way to show another site's page via Drupal? I have a somewhat odd request and, while I hate asking vague questions, I just don't know where to start with this one.

I am developing a website (Drupal 6) for a user that also has a seperate website with some very particular server side apps that allow their staff to do data entry.

The request is that they would like to show a certain data entry form from within the new site. The data entry form can span several pages but once done shows a very definitive End of Form marker. I am thinking that to simply show the form can be done using iFrames, perhaps. But this requested level of integration of having the current site recognize the end of form marker puzzles me.

Any advice on how to:


Show the data entry form from the other site.
Have Drupal recognize the "End of Form" marker (just some text that says Done, basically) would be very much appreciated.


Googling things like "Drupal show another page" and such doesn't yield much.
You should be able to use this.  Enable PHP code mode and paste it into a page:

&lt;?php
  $curl_handle = curl_init();
  curl_setopt($curl_handle,CURLOPT_URL,"http://www.google.com");
  curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2);
  curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1);
  $html = curl_exec($curl_handle);
  curl_close($curl_handle);
  print $html;
