12 Depending on the command line arguments, condor_urlfetch sends the
13 result of a query from the url to both standard output and to a file
14 specified by local-url-cache-file , or it sends the contents of the
15 file specified by local-url-cache-file to standard output.
16
17 condor_urlfetch is intended to be used as the program to run when
18 defining configuration, such as in the nonfunctional example:
19
20 LOCAL_CONFIG_FILE = $(LIBEXEC)/condor_urlfetch -$(SUBSYSTEM) \
21 http://www.example.com/htcondor-baseconfig local.config |
22
23 The pipe character ( | ) at the end of this definition of the location
24 of a configuration file changes the use of the definition. It causes
25 the command listed on the right hand side of this assignment statement
26 to be invoked, and standard output becomes the configuration. The value
27 of $(SUBSYSTEM) becomes the daemon that caused this configuration to
28 be read. If $(SUBSYSTEM) evaluates to MASTER , then the URL query
29 always occurs, and the result is sent to standard output as well as
30 written to the file specified by argument local-url-cache-file . When
31 $(SUBSYSTEM) evaluates to a daemon other than MASTER , then the URL
32 query only occurs if the file specified by local-url-cache-file does
33 not exist. If the file specified by local-url-cache-file does exist,
34 then the contents of this file is sent to standard output.
35
36 Note that if the configuration kept at the URL site changes, and recon‐
37 figuration is requested, the -<daemon> argument needs to be -MASTER .
38 This is the only way to guarantee that there will be a query of the
39 changed URL contents, such that they will make their way into the con‐
40 figuration.
41
43 -<daemon>
44
45 The upper case name of the daemon issuing the request for the con‐
46 figuration output. If -MASTER , then the URL query always occurs.
47 If a daemon other than -MASTER , for example STARTD or SCHEDD ,
48 then the URL query only occurs if the file defined by local-url-
49 cache-file does not exist.

57 and non zero otherwise.
