Q: 

Can i 'hold' POST data in ASP.NET, so i can verify with Captcha?

I have a complex page with maybe a dozen POST element and a file upload (non ajax ATM). I have a form with a description, if it causes akismet to find it as spam i would like the user to be informed and either hit back on their browser to try again or to hold call POST data so the user can fill in a reCaptcha to bypass the spam marking.

How do i hold the POST data? i have no idea how to redirect the user to this captcha page and to keep all the post data. It would be preferable if it was generic and i didnt need to copy the post and get data by hand.

One solution could be to create hidden form fields with all received data. This is easy to do it generically, just iterate through all $_POST elements and create a new hidden field for each one. Obviously you must create a valid form. Once this new page is loaded you should redirect to desired location.

I'm not sure that using a hidden field for an image will make sense. You can save the image (and everything else) on disk and put its location in session or in a cookie so you can find it later, among other options.

I think he is not asking to keep the image from page to page but data from a form.
