Can I search and replace part of the uri with irule?

For example

 

 

HTTP/1.1 302 Redirect

 

Date: Fri, 08 Apr 2005 01:01:13 GMT

 

Server: Microsoft-IIS/6.0

 

Location:

 

https://xxx.xxx.net/obrareq.cgi?t%3D0%20o%3D%20no%3D%20r%3D%2

 

0nr%3D%20wu%3D%2Fportal%2Fsso%2FSSOLogin.aspx%20wh%3Dx.x.x.x%20wo%

I need the "http" within the uri be "https"
