PHP script to bypass most CPAlead survey.
Works like a proxy for the page only (ie. not images) - strips CPAlead code from pages and then dishes them up.
Features:
- To avoid usage as a proxy:
- Sends user's IP with page request in HTTP header and URL.
- Checks url and page content against a keyword blacklist.
- Won't display a page which didn't originally have a survey on it.
- Other Features:
- Rewrites other, same-domain links on page so that they will be bypassed too.
- Rewrites relative URLs to absolute URLs (to prevent broken images, stylesheets, etc.)
- Form completes URLs missing a 'http://' or 'https://' prefix on submission.
- Terms of Service page.
