| 17 | .Sh DESCRIPTION |
||
| 18 | .Nm |
||
| 19 | is the backend process in the Prayer Webmail system. A fresh |
||
| 20 | .Nm |
||
| 21 | backend is forked off whenever a user logs in. |
||
| 22 | .Pp |
||
| 23 | This process contains all of the permanent state associated with that login |
||
| 24 | session including one or more connections to a IMAP server and possibly |
||
| 25 | connections to accountd servers. prayer-session communicates with the user |
||
| 26 | using HTML over HTTP connections via the |
||
| 27 | .Xr prayer 8 proxy. Each login has a session ID that the front end processes |
||
| 28 | use to find the correct backend. |
||
| 29 | .Pp |
||
| 30 | Backend server processes move into a dormant state after a certain period |
||
| 31 | of inactivity, shutting down IMAP and accountd connections which can be |
||
| 32 | easily resuscitated when the session wakes up. After a long period of |
||
| 33 | inactivity, typically several hours the session process shuts down. |
||
| 34 | .Pp |
