Question about URL parameter and Cookie?

cheetahogreen said:

The %3D is the URL-encoded version of the = symbol, which happens when the value is URL-encoded before being placed into the cookie.

Hi, I have a URL parameter that contains this and it's being put into a cookie as well in the browser.

?clickid=CPOly7oGENUHGNu28uEDILOLzOIHKIYdMNUHOgJVU0ICQ0FKC0xvcyBBbmdlbGVzUgExYhB8zzoDwfdMIYEcgoQsvQ1KagNPUkRyIjliOWNiZjE1ZDg2NjQ5MDRiMDhlMWFmNTFlZjg3ODA3LTI=

However, when I look at the cookie it put into the browser, it's showing this:

CPOly7oGENUHGNu28uEDILOLzOIHKIYdMNUHOgJVU0ICQ0FKC0xvcyBBbmdlbGVzUgExYhB8zzoDwfdMIYEcgoQsvQ1KagNPUkRyIjliOWNiZjE1ZDg2NjQ5MDRiMDhlMWFmNTFlZjg3ODA3LTI%3D

Everything matches, but for some reason at the VERY END when the cookie is inserted it's adding %3D vs =?
