JIRA sets cookies to 'remember' the state of some screens, e.g. the state of sections on Issue Navigator and the right-hand menu of the Administration section. There is a limitation of the number of cookies that a web browser will send to a particular server (URL). Hence we need to restrict the amount of cookies set.

There are several options to investigate:

• see if we can unify some cookies into one and encode the information in one cookie
• see if we can restrict a cookies only to certain URLs (all cookies do not need to be sent for each JIRA URL)
• as some cookies are only used by JS and do not need to be sent, we can try restricting a cookie to a URL in JIRA that does not exis, to stop the browser from sending the cookies. In this case need to ensure that JS can still access these cookies.
