IIS URL Encoding issue. IIS replaces & to $$

Hi there!

I have a problem with encoding in ASP.Net web server (IIS 7.0).

When I'm trying to proceed the link server replaces ampersand (&) to 2 dollar ($) symbols.

Example:

http://example.com/example.aspx?param1=a&param2=b

Becomes

http://example.com/example.aspx?param1=a$$param2=b

How can I resolve this issue?

Thanks in advance!
