ns_geturl.3aolserver

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.
