Have a look at this part: VaryByParam="CID"
Any idea what that means? Have a look at the details of Vary-by-param caching here: @ OutputCache[^]
Caching Versions of a Page, Based on Parameters[^]

You get back the value as 123 as caching is varied by 'CID' querystring value.

I already shared the sample project and material. Read and look at them.
It's caching, do an IIS Reset and retry with new value just in case.

Sandeep is right, you forgot the thing in the code. You must take a look at this article which is well written.
