Hey all!

Can anyone provide a specific definition of "CHECKSUM", used in a URL and how it can be used?

Thank you!

I've got some information about the checksum :

---
IN GENERAL, A CHECKSUM IS A VALUE TO CHECK THE VALIDITY OF SOMETHING
---

---
IN APEX, THIS VALUE IS GENERATED BY APEX TO PREVENT TAMPERING WITH URLS. A URL WITH CHECKSUM HAS THE FOLLOWING FORM:
127.0.0.1:8080/apex/f?p=200:9:2546128677760790::NO::p9_user_name:test&cs=3658F2C0D9A52D3D80206C5943442044A.
THE BOLD VALUE IS A CHECKSUM
---

So I don't think anyone can provide such value to access restricted pages or data using URLs.

N.B. Many thanks to Mr. Patrick Wolf . . .
