Thanks Dmitriy - I'll pass that comment on to Charles who would know what your talking about.

I was testing the form, got the bad request notice, logged on to respond here and got the stop error and memory dump thing.

This form is interacting with another server which has an intranet of sorts that my client works with. Basically the application, when submitted goes into their program they use for property management.
What we ran into, is if the captcha code was input incorrectly (at the very end of an excruciating form) the form processor reloaded the form page and everything entered was gone. Charles has gotten the form to break into multiple pages with a quick save feature which is what he mentions at the beginning of the thread.

I think he's using AJAX and php sessions combined to allow the user to come back within 30 days and continue with the application. I'll let Charles think this out and get out of your guys' way...

Thanks again Dmitriy.
