We have websites on multiple sub-domains that work together quite seamlessly, e.g. pages from account or billing are loaded into iFrames onto other sites. We use the same Raygun API key on all of them to track usage in a single Raygun Application, but Raygun currently tracks visits to each site as a separate session. It would be good if this could be merged.
I assume it would mean including an option to set session cookies on domain rather than sub-domain level.
