Custom Track Storage

• each session (=hgsid) has a list of key=value entries that are called the "cart"
• the session carts are stored in the "session" table in hgcentral
• sessions with custom tracks have an entry "ctfile" in the cart that points to a file in the trash folder that has the "track" lines of the custom tracks
  • remember that you can use /cgi-bin/cartDump to show this variable
  • you can then display the ctfile and use it to convert custom tracks to track hubs if really needed
• special case: for named sessions, the ctfile files are moved to /userdata/ct/rr at some point
• by opening the ctfile you can see pointers to tables in the customtrash database, these are table names
