HTTP request using hash.

Question

I am reading about making my ajax application crawlable. According to google's doc, i need to change my http requests using hash, so from:

http://www.example.com/get_data?param1=6

to

http://www.example.com/get_data#!param1=6

I honestly don't get how #! could be handled by my server and parameters taken. So this makes me thinking i have don't understood the general concept. How can i pass parameters using hashes instead of '?'

thank you

Afaik, you can't, at least not by using generic GET requests. The hash will not be transferred to the server. Please someone correct me in case I am wrong. — nilsole, Apr 07 '14 at 14:09
Your server can't read the hash on the server. This is out dated technique. Learn about the history api — epascarello, Apr 07 '14 at 14:09
not sure, but i think it would not handled by server side automatically, you must pass it by yourself using javascript methods. — Unstaged, Apr 07 '14 at 14:09
Maybe you can post a link to the Doc you are referring to. Thanks. :) — nilsole, Apr 07 '14 at 14:11
>so what google means while talking about this? as I remember it is just advice from google to developers, who cares about SEO and correctly indexing their links, because simple hash site.com/page.php#somevar will be ignored by google — Unstaged, Apr 07 '14 at 14:11
Not sure about the whole concept, but there are is some information about it at point 2 here in this doc: https://developers.google.com/webmasters/ajax-crawling/docs/getting-started — nilsole, Apr 07 '14 at 14:14
If Google says to change a URI not containing a "#" to a URI containing a "#" then they are very very wrong. — Julian Reschke, Apr 07 '14 at 14:54

The hash is something handled exclusively by JavaScript, which then makes a normal Ajax request. This StackOverflow question gives you some info on how you can detect changes in the Hash using JavaScript. Once the hash has changed:

var queryString = window.location.hash.replace(/^#/, "");
var xhr = new XMLHttpRequest();
var url = "/foo?" = queryString;

xhr.onreadystatechange = function() {
    ...
};

xhr.open("GET", url);
xhr.send(null);

HTTP request using hash.
