LlHTTPRequest

Sends an HTTP request to the specified URL with the body of the request and parameters.

Returns a key that is a handle identifying the HTTP request made.

key http_request_id;
 
default
{
    state_entry()
    {
        http_request_id = llHTTPRequest("url", [], "");
    }
 
    http_response(key request_id, integer status, list metadata, string body)
    {
        if (request_id == http_request_id)
        {
            llSetText(body, <0,0,1>, 1);
        }
    }
}

Example PHP test script:

<?php header("content-type: text/plain; charset=utf-8"); ?>
Headers received:
<?php
 
/**
 * @author Wouter Hobble
 * @copyright 2008
 */
 
foreach ($_SERVER as $k => $v)
{
	if( substr($k, 0, 5) == 'HTTP_')
	{
		print "\n". $k. "\t". $v;
	}
}
?>

example wrapper script Both capturing apache headers and global methodes

 
<?PHP
	// Author Waster Skronski.
	// General Public License (GPL).
	// Mind that some headers are not included becouse they either useless or unreliable.
	$USE_APACHE_HEADERS = TRUE; // switch to false if you need cgi methode
	if ($USE_APACHE_HEADERS)
	{
		$headers 	= apache_request_headers();
		$objectgrid 	= $headers["X-SecondLife-Shard"];
		$objectname 	= $headers["X-SecondLife-Object-Name"];
		$objectkey     	= $headers["X-SecondLife-Object-Key"];
		$objectpos 	= $headers["X-SecondLife-Local-Position"];
		$ownerkey     	= $headers["X-SecondLife-Owner-Key"];
		$ownername 	= $headers["X-SecondLife-Owner-Name"];
		$regiondata     = $headers["X-SecondLife-Region"];
		$regiontmp 	= explode ("(",$regiondata); // cut cords off 
		$regionpos 	= explode (")",$regiontmp[1]); //
		$regionname 	= substr($regiontmp[0],0,-1); // cut last space from simname
	} else {
		$db = $GLOBALS;
		$headers 		= $db['HTTP_ENV_VARS'];
		$objectgrid 	= $headers["HTTP_X_SECONDLIFE_SHARD"]; 
		$objectname 	= $headers["HTTP_X_SECONDLIFE_OBJECT_NAME"];
		$objectkey     	= $headers["HTTP_X_SECONDLIFE_OBJECT_KEY"];
		$ownerkey     	= $headers["HTTP_X_SECONDLIFE_OWNER_KEY"];
		$objectpos     	= $headers["HTTP_X_SECONDLIFE_LOCAL_POSITION"];
		$ownername 	= $headers["HTTP_X_SECONDLIFE_OWNER_NAME"];
		$regiondata     = $headers["HTTP_X_SECONDLIFE_REGION"];
		$regiontmp 	= explode ("(",$regiondata); 
		$regionpos 	= explode (")",$regiontmp[1]);
		$regionname 	= substr($regiontmp[0],0,-1);
	}
?>
 

If for some reason while using llHTTPRequest/http_response you are unable to parse a known good RSS feed or some other form of web contents, you will need to work around it outside of SecondLife. This is unlikely to change in the near future since checking the headers requires more overhead at the simulator level.

CGI environments may place the headers into variables by capitalizing the entire name, replacing dashes with underscores, and prefixing the name with "HTTP_", e.g. "HTTP_X_SECONDLIFE_OBJECT_NAME".

Apache can include the headers in its logs, using the CustomLog and LogFormat directives. See the docs for details on the syntax.
