How to upload to my host other people sites?

I mean, I want to host in my own host another site I am affiliate with.

Example:

Original site: www.anothersite.com/?=myaffiliatelink

My site: www.mydomain.com/anothersite

I want to mask my affiliate link and host the other site in my own host..

How to do that?

Thank a lot

 

So do you want to like create a redirect to the "original site"? Or would you literally like to "host the other site in [your] own host"?

If you just want to redirect you could use some clever scripting to do the trick
