I need a javascript form filler that can bypass the 'same origin policy' most modern browsers implement.
I made a script that opens the desired website/form in a new browser. With the handler, returned by the window.open method, I want to retrieve the inputs with theWindowHandler.document.getElementById('inputx') and fill them (access denied).
Is it possible to solve this problem by using Isapi Rewrite (official site) in IIS 6 acting like a reverse proxy?
If so, how would I configure the reverse proxy?
This is how far I got:
RewriteEngine on
RewriteLogLevel 9
LogLevel debug
RewriteRule CarChecker https://the.actualcarchecker.com/CheckCar.aspx$1 [NC,P]
The rewrite works, http://ourcompany.com/ourapplication/CarChecker, as evident in the logging. From within our companysite I can run the carchecker as if it was in our own domain. Except, the 'same origin policy' is still in force.
