Help with mod_rewrite

Hi,I am new to this forum and this is my first post here.I couldn't find a category for Apache or servers, so I am posting it here (PHP is most synonymous with Apache, I believe!)My question is that can I use mod_rewrite to show pages from another server, yet making my visitors believe that they are actually on my server?For example, say I have a server abcd.com, but I want visitors to see content from xyz.com/asdf/index.php?id=256, but the browser's location bar should still display abcd.com.Is it possible using mod_rewrite? I am a bit confused if flag [P] can be used to achieve this or not.Please let me know if this can be achieved.Thanks

PHP is most synonymous with Apache
Huh? Apache is a server operating system, and PHP is a programming language. However, apache servers commonly have PHP interpreters...mod_rewrite is an apache feature, not a PHP one.
Is it possible using mod_rewrite?
I don't think so, as as soon as you navigated away from the site the rule could not apply any more. You are better of creating a PHP proxy...

You could map the URLs to a single PHP file and a single query string parameter (called "uri" in the sample below) in which you'll have

<?phpfile_get_contents('http://abcd.com' . $_GET['uri']);?>

This will fetch all contents from the remote site as is and show it to the user. If you need anything more though, you'll really have to use a PHP proxy. A PHP proxy is again a PHP file similar to this, but it processes the contents it fetches to ensure certain things to the user such as correct image paths, cookies and so on.

Heh - like this super simple proxy I developed recently (it is rather hopeless, can handle internal relative links and some get-type forms, external stylesheets and scripts, but not absolute linking, post forms, cookies and sessions, or images:proxy.php

<?php	function rmv2slash($string) {		return str_replace(":/", "://", str_replace("//", "/", $string));	}	if (isset($_GET['address'])) {		$raw_address = $_GET['address'];		$address = urldecode($raw_address);		echo "<!-- Current page: $address -->\n";		$i = (strstr($address,"?")) ? true : false;		foreach($_GET as $get_key => $get_value) {			if ($get_key != "address") {				$address .= (($i) ? "&" : "?") . "$get_key=$get_value";				$i = true;			}		}		$address = rmv2slash($address);		$display_address = $address;		if ($page = file_get_contents($address)) {			if (substr($address,-1,1) != "/" && substr($address, 0, 1) != "?") {				$address = substr($address, 0, strpos($address, strrchr($address, "/")) + 1);			}			preg_match_all("/<link(.*?)type=\"text\/css\"(.*?)href=\"(.*?)\"(.*?)>/i", $page, $css_files);			foreach ($css_files[3] as $css) {				$page = preg_replace("/<link(.*?)href=\"" . preg_quote($css, "/") . "\"(.*?)>/i", "<style type=\"text/css\">\n" . file_get_contents($address . $css) . "\n</style>", $page);			}			preg_match_all("/<script(.*?)src=\"(.*?)\"(.*?)>(.*?)<\/script>/i", $page, $scripts);			foreach ($scripts[2] as $script) {				//echo "@@@ $script @@@";				$page = preg_replace("/<script(.*?)src=\"" . str_replace("/", "\/", $script) . "\"(.*?)>(.*?)<\/script>/i", "<script type=\"text/javascript\">\n". file_get_contents(rmv2slash($address . $script)) . "\n</script>", $page);			}			$page = preg_replace("/<a (.*?)href=\"(.*?)\"(.*?)>/i", "<a $1" . "href=\"?address=" . ((stristr("http://", "$2")) ? "$2" : "{$address}$2") . "\"$3>", $page);			$page = preg_replace("/<form (.*?)action=\"(.*?)\"(.*?)(method=\"get\")?(.*?)>/i", "$0<input type=\"hidden\" name=\"address\" value=\"{$address}$2\">", $page);			$page = preg_replace("/<form (.*?)action=\"(.*?)\"(.*?)>/i", "<form $1" . "action=\"" . substr($_SERVER['PHP_SELF'], 1) . "\"$3>", $page);			$page = preg_replace("/<body(.*?)>/i", "$0<div style=\"display:static; width:100%; background-color:#EEEEEE; padding:10px; margin-bottom:10px; text-align:center; font-family:arial; font-size:10pt; color:#000000; \"><form action=\"{$_SERVER['PHP_SELF']}\" method=\"get\" style=\"width:80%; \"><b>Super Simple Proxy</b><br /><input type=\"text\" name=\"address\" value=\"{$display_address}\" style=\"width:100%; \" /></form></div>", $page);			echo $page;		} else {			echo "Error: The page you requested could not be retreived.";		}	} else {		echo "<div style=\"display:static; width:100%; background-color:#EEEEEE; padding:10px; margin-bottom:10px; text-align:center; font-family:arial; font-size:10pt; \"><form action=\"{$_SERVER['PHP_SELF']}\" method=\"get\" style=\"width:80%; \"><b>Super Simple Proxy</b><br /><input type=\"text\" name=\"address\" style=\"width:100%; \" /></form></div>";	}?>
