PHP POST interceptor

I have a form that my users must fill out. I send (via POST) this form's data to a third party website. Unfortunately, the third party website has elected to identify me by the use of sensitive fields in my form. Their idea of security is hiding the fields. I really don't like the idea of putting this information on my site for the world to see, even if the form fields are hidden. One more thing. I have already created a workaround that writes a new form momentarily to the browser, then immediately POSTs to the target page. Although clever, it is not foolproof, because I do write a new form with the sensitive values in the HTML. This is not an acceptable solution. Also, you can't use CURL. YOUR MISSION: Create an intermediate script that will intercept the POST, read the post variables, change the values in the specified fields, then deliver the submitter and the POSTed variables to the target page using a POST. This last point is important. You cannot use fsockopen() to POST the variables to the page and return the target page output. No, my friends, the page you create must actually navigate the browser to the target page, and deliver both the user and the POSTed variable values. You must use PHP. Please call your creation "[login to view URL]" I have created my demonstration form, called [login to view URL], and a development purposes only target form, target.php. This is to demonstrate that the form works, and what I expect the output to look like. I have also created [login to view URL], which is identical to [login to view URL], except that it posts to your script, [login to view URL], which does the work that I've asked for. Use this for your development. None of my code should change. Your best chance of winning the bid is to do the work, make it available on a URL, and name your reasonable price. I will test your work on my servers before payment. I thank you for your interest. Check my references, I answer questions quickly and pay promptly! Thanks! ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Complete ownership and distribution copyrights to all work purchased. ## Platform PHP 4.2.3, Linux ## Deadline information I will test robustly before acceptance.
