Documentation for JIRA 4.4. Documentation for other versions of JIRA is available too.
If you have set up project links to more than one project in the same application, for example you have linked your JIRA project to two Confluence spaces, then one of the project links will be marked as the primary link. All outgoing requests will be directed to the primary link.
For example, if you have a JIRA project that is linked to two Confluence spaces, you can nominate the link to Confluence spaces as the primary link. Every time JIRA requests Confluence information, it will request it from the primary link's Confluence space. Note, both Confluence spaces can still request information from the JIRA project.
The information on this page does not apply to JIRA OnDemand.
