I am trying to write a small web application to do the following:
You want to browse a URL "http://www.google.com".
You enter this URL in a form. (In Form.aspx or whatever)
The form will do a basic encryption on the URL (like shift each character one way, like "H" becomes "I" etc.), then redirect to another page with a link like this: "http://www.mydomain.com/View.aspx?url=iuuq://xxx.hpphmf.dpn"
Now View.aspx will decrypt the given URL to "http://www.google.com", it will read the requested page using the following:
So now I have the page contents in a stream reader. Now I want to go through the contents and encrypt all links (same encryption as above), then output the page to the viewer.
Now it gets harder: All links on the page being viewed should now point to "http://www.mydomain.com/View.aspx?url=xyxyxyx", where "xyxyxyx" is the encrypted link. If the link is to a binary file, like an image or something, how do I output that normally without going through the whole encryption/decryption process?
So View.aspx should be able to output ANY webpages with all links encrypted, as well as normal binary files like images etc.
Any help would be appreciated!
