package require http

   proc getPage { url } {
        # no cleanup, so we lose some memory on every call
        return [ ::http::data [ ::http::geturl $url ] ]
   }

   set file [ getPage $url ]

The above is a basic example of the [http] package.  It however doesn't account for proxys,
URL redirects, etc.  See [grabchat] for code which tries to 
handle some additional issues.

Some further examples can be found at the [http] page.

The example above ommits cleanup, so memory consumption rises when you use it to get many pages. The example below cares for cleanup.

 package require http
 proc getPage { url } {
       set token [::http::geturl $url]
       set data [::http::data $token]
       ::http::cleanup $token          
       return $data
 }
