Method Details [hide private]

__init__(self)
(Constructor)

source code 
Overrides: spacewalk.common.rhnApache.rhnApache.__init__

_setSessionToken(headers)
Static Method

source code 

Pushes token into rhnFlags. If doesn't exist, returns None. Pull session token out of the headers and into rhnFlags.

Overrides: spacewalk.common.rhnApache.rhnApache._setSessionToken
(inherited documentation)

headerParserHandler(self, req)

source code 

Name-munging if request came from anaconda in response to a kickstart.

Overrides: spacewalk.common.rhnApache.rhnApache.headerParserHandler

_transformKickstartRequest(self, req)

source code 

If necessary, this routine will transform a "tinified" anaconda- generated kickstart request into a normalized form capable of being cached effectively by squid.

This is done by first making a HEAD request to the satellite for the purpose of updating the kickstart progress and retrieving an MD5 sum for the requested file. We then replace the tinyURL part of the URI with the retrieved MD5 sum. This effectively removes session-specific information while allowing us to still cache based on the uniqueness of the file.

_querySatelliteForChecksum(self, req)

source code 

Sends a HEAD request to the satellite for the purpose of obtaining the checksum for the requested resource. A (status, checksum) tuple is returned. If status is not apache.OK, checksum will be None. If status is OK, and a checksum is not returned, the old BZ 158236 behavior will be used.

_generateCacheableKickstartURI(oldURI, checksum)
Static Method

source code  

This routine computes a new cacheable URI based on the old URI and the
checksum. For example, if the checksum is 1234ABCD and the oldURI was:

    /ty/AljAmCEt/RedHat/base/comps.xml

Then, the new URI will be:

    /ty-cksm/1234ABCD/RedHat/base/comps.xml

If for some reason the new URI could not be generated, return None.

handler(self, req)

source code 

Main handler to handle all requests pumped through this server.

Overrides: spacewalk.common.rhnApache.rhnApache.handler

cleanupHandler(self, req)

source code 

Clean up stuff before we close down the session when we are called from apacheServer.Cleanup()

Overrides: spacewalk.common.rhnApache.rhnApache.cleanupHandler
