ns_geturl(3)

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 con

taining 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.
