+2  Q: 

About what percentage of Internet users have referrers turned off?

I'm making something that requires me to pass information from one domain to a subdomain. The subdomain would be in an iframe on the domain. I know I can use cookies, sessions, or a database. But I'm trying to save processing time so I thought about using the referrer. I know that some people turn the referrer off for some reason, but exactly just how many. If they do, this won't work for them.

Oh and I can't use the URL to pass information.

+1  A: 

I'd say < 0.001 % of all Internet users have ever heard about referrers. Even a smaller portion of them will be willing to switch them off. Even a smaller number of them will be able to.
