Cache of interlinked URLs

[$ubbu]

Hi All,

     I'm giving an example of the scenario

we created a global DNS entry for www.golfradar.com pointing to local ip:
192.168.0.51

I wrote a rule in remap.config like map http://www.golfradar.com/
http://golfpunk.golfradar.com

here golfpunk.golfradar.com needs to get data from other sites (ex:from
www.pgatour.com..)

My question is can we cache the data from www.pgatour.com also without
adding the site in host file or local dns??
