BACKGROUND

A website of mine was recently the target of a conditional redirect attack.

• PHP code was added to my pages to redirect visitors.
• The .htaccess file was edited to redirect visitors.

I've re-uploaded my website so the compromised PHP and .htaccess code have both been removed.

My site is mostly handwritten php and static HTML content. I don't use page comments or any third party libraries.

THE PROBLEM

After removing the compromised php and htaccess files, visitors are still being re-directed.

• What could be the reason that visitors are still being redirected?
• Are there any tools to check where/how redirects are taking place so I can debug the problem?

UPDATE - PROBLEM FIXED

As suggested in the comments, I cleared my Firefox cache and that fixed the problem (for me anyway). Visitors with old cache data will obviously still be re-directed.
