12 [ -s ] [ -p ssf ] [ -q ]
13
15 httpd is an HTTP server. It accepts commands on its standard input and
16 responds on its standard output. It MUST be invoked by master(8) with
17 those descriptors attached to a remote client connection.
18
19 httpd reads its configuration options out of the imapd.conf(5) file un‐
20 less specified otherwise by -C.
21
22 If the directory <configdirectory>/log/user exists, then httpd will
23 create protocol telemetry logs for sessions authenticating as user. The
24 telemetry logs will be stored in the log/user directory with a filename
25 of the httpd process-id.
26
28 -C config-file
29 Use the specified configuration file config-file rather than the
30 default imapd.conf(5).
31
32 -U uses
33 The maximum number of times that the process should be used for
34 new connections before shutting down. The default is 250.
35
36 -T timeout
37 The number of seconds that the process will wait for a new con‐
38 nection before shutting down. Note that a value of 0 (zero)
39 will disable the timeout. The default is 60.
40
41 -D Run external debugger specified in debug_command.
42
43 -s Serve HTTP over SSL (https). All data to and from httpd is en‐
44 crypted using the Secure Sockets Layer.
45
46 -p ssf Tell httpd that an external layer exists. An SSF (security
47 strength factor) of 1 means an integrity protection layer ex‐
48 ists. Any higher SSF implies some form of privacy protection.
49
50 -q Ignore quotas on DAV appends. This feature was introduced in
51 version 3.0.
52
54 httpd is commonly included in the SERVICES section of cyrus.conf(5)
55 like so:
56
57 SERVICES {
58 imap cmd="imapd -U 30" listen="imap" prefork=0
59 imaps cmd="imapd -s -U 30" listen="imaps" prefork=0 maxchild=100
60 lmtpunix cmd="lmtpd" listen="/var/run/cyrus/socket/lmtp" prefork=0 maxchild=20
61 sieve cmd="timsieved" listen="sieve" prefork=0
62 notify cmd="notifyd" listen="/var/run/cyrus/socket/notify" proto="udp" prefork=1
63 httpd cmd="httpd" listen=8080 prefork=1 maxchild=20
64 }
65
67 A beta release of httpd was first introduced in the caldav branch of
68 Cyrus in version 2.4.17, and was included in the mainline releases be‐
69 ginning in version 2.5.0.
70
71 The quota override option, -q, was introduced with Cyrus version 3.0.
