Hi Gurus
I have a very small issue but I don't have any knowledge about it, so its getting to my nerves...

I would like to get values from the URL and make it available on the entire site.

The Flow is like shown below
1. posting of data from site 1 to site 2
2. Capture of data in Site 2
3. Using couple of variables from the Captured data in entire site

ISSUE .

1. Able to capture Data in homepage (Default.aspx)
2. BUT not able to make it available in any part of the site...

Solutions Tried with my basic skills....

1. Hidden Fields
2. Session
3. Cookies

RESOLUTION SO FAR:

ZERO

Files used in the site

Default.aspx (Home Page)
Default.aspx.cs (Background)
Editor.JS (Script for running)
Canvassave.aspx
CanvasSave.aspx.cs(THE MOST MESSY FILE - and this is where I would like to have the variables)

List of VAriables Needed
For NOW - 2 [ ID, NAME ]

REASON
Would like to create unique folders and sharing files
