Name
       condor_urlfetch fetch - configuration given a URL


Synopsis
       condor_urlfetch [-<daemon>] urllocal-url-cache-file


Description
       Depending  on  the command line arguments, condor_urlfetchsends the result of a query from the urlto both
       standard output and to a file specified by local-url-cache-file, or it sends the  contents  of  the  file
       specified by local-url-cache-fileto standard output.

       condor_urlfetchis  intended  to be used as the program to run when defining configuration, such as in the
       nonfunctional example:

       LOCAL_CONFIG_FILE = $(LIBEXEC)/condor_urlfetch  -$(SUBSYSTEM) \

        http://www.example.com/htcondor-baseconfig  local.config |

       The pipe character ( | ) at the end of this definition of the location of a  configuration  file  changes
       the  use  of  the  definition.  It  causes  the  command listed on the right hand side of this assignment
       statement to be invoked, and standard output  becomes  the  configuration.  The  value  of   $(SUBSYSTEM)
       becomes  the  daemon  that  caused this configuration to be read. If  $(SUBSYSTEM) evaluates to  MASTER ,
       then the URL query always occurs, and the result is sent to standard output as well  as  written  to  the
       file  specified  by  argument  local-url-cache-file.  When  $(SUBSYSTEM) evaluates to a daemon other than
       MASTER , then the URL query only occurs if the file specified by  local-url-cache-filedoes  notexist.  If
       the  file specified by local-url-cache-filedoes exist, then the contents of this file is sent to standard
       output.

       Note that if the configuration kept at the URL  site  changes,  and  reconfiguration  is  requested,  the
       -<daemon>argument  needs to be  -MASTER . This is the only way to guarantee that there will be a query of
       the changed URL contents, such that they will make their way into the configuration.


Options
       -<daemon>

          The upper case name of the daemon issuing the request for the configuration output. If  -MASTER , then
          the  URL  query always occurs. If a daemon other than  -MASTER , for example  STARTD or  SCHEDD , then
          the URL query only occurs if the file defined by local-url-cache-filedoes not exist.


Exit Status
       condor_urlfetchwill exit with a status value of 0 (zero) upon success and non zero otherwise.
