Answer 1

This is often caused by overcautious settings of mod_security, an Apache extension. You'll have to consult your provider. (But they usually disable this individually or relax the settings.)

Answer 2

Since characters like : and / etc are special characters in URLs, you cannot use them as part of a query string like that. You need to encode what you are passing in as a URL - in php that is done by the urlencode function, and will look like this:

test.php?url=http%3A%2F%2Fgoogle.com

Answer 3

I added SecFilterEngine Off to .htaccess . and it solved the problem it's basically mod_security .
