Truly there is no reason to have to redirect anything for this to work. The instructions tell you to upload the "contents" of the folder that the program creates to the location that the page the form is on resides. If you do this then there is no need to edit anything to do with the structure of the form other than changes you may want to do for aesthetics.
Granted, you "can" edit the links and paths etc., just saying if you do it the way the program tells you there is no need to change anything and your page won't get overwritten because the program doesn't save the form directly to your page's directory, it saves the folder it creates to that directory, and the folder holds the contents you need to put where your page is.
Much easier than it looks I think.
