How to store a value through out the route without re initializing it

[djugal]

Hi,

I have a simple Route which calls a job.

One of the job part creates a random key each time if it is null. After which the key is stored in a context.

So, each time the route calls the job contexts are reset and a new random key has be generated.

Can we somehow store/preserve this context or generated key throughout the route, so it needs not be generated again.
