Crawlable AJAX with _escaped_fragment_ in htaccess

Question

Hello fellow developers!

We are almost finished with developing first phase of our ajax web app. In our app we are using hash fragments like:

http://         


        

Answer 1

Your forgot QSA directive (everyone missed the point =D )

RewriteCond %{QUERY_STRING} ^_escaped_fragment_=(.*)$
RewriteRule ^$ /webroot/crawler.php%1 [QSA,L]

By the way your $1 is well err... useless because it refers to nothing. So this should be:

RewriteCond %{QUERY_STRING} ^_escaped_fragment_=(.*)$
RewriteRule ^$ /webroot/crawler.php [QSA,L]

Tell me if this works.

Answer 2

Maybe is obvious for you, but in the documentation talk about escaped characters: Set up your server to handle requests for URLs that contain

The crawler escapes certain characters in the fragment during the transformation. To retrieve the original fragment, make sure to unescape all %XX characters in the fragment. More specifically, %26 should become &, %20 should become a space, %23 should become #, and %25 should become %, and so on.

Answer 3

Here is a solution that provides a routable URL and query parameters correctly set for processing in the server side script.

Example: If you want http://yoursite.com/#!/product/20 to become http://yoursite.com/crawler/product/20

First in .htaccess

RewriteCond %{QUERY_STRING} ^_escaped_fragment_=(.*)$
RewriteRule ^$ /crawler/index.php?_frag=%1  [L]

We need to get rid of the _escaped_fragment_ in the URL and replace it with something different, example: _frag so that the (Apache) web server does not get in to circular rewrites.

Second in crawler/index.php

<?php

if(array_key_exists('_frag', $_REQUEST)) {
    $_SERVER['REQUEST_URI']=$_REQUEST['_frag'];
    unset($_REQUEST['_frag']);
    parse_str($_SERVER['QUERY_STRING'], $frag); 
    parse_str(preg_replace('/^.*\?/', '', $frag['_frag']), $_REQUEST);
    $_SERVER['QUERY_STRING'] = http_build_query($_REQUEST);
}

// Continue with your usual script of routing
// $_REQUEST now contains the original query parameters

In htacess work in virtual host not working, so i add in "directory"

<Directory "X:/DIR">
    RewriteEngine On
    RewriteCond %{QUERY_STRING} ^_escaped_fragment_=(.*)$
    RewriteRule ^$ /crawler/index.php?_frag=%1  [L]
</Directory>

Answer 5

If I'm not mistaken.

RewriteCond %{QUERY_STRING} ^_escaped_fragment_=(.*)$
RewriteRule ^$ /webroot/crawler.php?%1 [L]
