How does position of parameters in a Query string affect the page?

Question

I have an application with most of the code written in javascript. I am encountering a strange problem. I have a query string and my app reads it to perform various actions.

Answer 1

I have seen that kind of problem when the developer used the query string, as is, as a key to a cached object. When the query string changed, the key was not the same and the cache mechanism was failing (due to another bug).
