cookieless session issue with the url

Question

when setting <sessionState cookieless="true"></sessionState> in my web.config, I am getting strange url, how can I get rid of this.

here is the my url:

myhost:1578/%28S%28vzozelw3hgtqi22ndvyndzn1%29%29/default.aspx

but it should be myhost:1578/default.aspx
