Use of while loop for condition evaluation

Should we use if instead?

Not sure about if statement, but there are other approaches that might be simpler. e.g. https://stackoverflow.com/questions/10730362/get-cookie-by-name

But to be honest, unless something is breaking, it might be better to keep this code as is. Not sure how much advantage there is by changing this part.

No problem. I just wanted to suggest a more efficient and elegant solution than using a loop for an evaluation.
