URL base32 extension

Hi Folks,

I do see some websites with extensions such as the one below where extra numbers and letters possibly on base 32 have been added to the URL.

Code:

---

http://www.mywebsite.com/index.php?lh=566057805f1cc3cc5885dde4cc663f32

---

If anyone has had experience in creating something like this, could they tell me how to achieve that with PHP, please?

Thanks,
Menre

What is it you want to do exactly? You can tack that on to any URL you want. But it depends what you want to do with it.

To get the "lh" string use $_GET

PHP Code:

---

$lh = $_GET['lh']; 


---

Looks like an MD5 hash sum.

Usually when one sees these in the query part of a URL it is a session identifier. The recommended way to transmit session identifiers is by using a cookie instead.

Thanks for your responses. Both of you have an idea of what I want to do and how to go about it. I will have to post a snippet of the problem at hand then so that you can help me better.
