NAME

       ns_geturl - commands

SYNOPSIS

       ns_geturl URL ?headersSetId?
_________________________________________________________________

DESCRIPTION

       This  command  retrieves  the contents of the specified URL. The URL must be a remote http
       server, or a file relative to the pageroot (begins with /).  It does not handle a relative
       request or follow redirects.  The headerSetId option is a variable containing an ns_set Id
       (not expanded with a $) used to store the remote server headers (see example).   ns_geturl
       only support HTTP version 1.0.

EXAMPLES

              set page [ns_geturl "www.aolserver.com"]
              ns_return 200 text/html $page

       This fetches the contents of www.aolserver.com and returns that page to the client.

              set headers [ns_set new]
              set page [ns_geturl "www.aolserver.com" headers]
              for {set i 0} {$i < [ns_set size $headers]} {incr i} {
                 ns_puts "Key: [ns_set key $headers $i]"
                 ns_puts "Value: [ns_set value $headers $i]"
              }

       This  time, a blank headerset is passed to ns_geturl so we can retrieve the headers of the
       remote page, which we print out to the client.

              set file [ns_geturl "/foo/bar.html"]
              ns_return 200 text/html $file

       This example fetches the /foo/bar.html file relative to the pageroot and returns it to the
       client.
