Class BrokerHandler

source code

Spacewalk Proxy broker specific handler code called by rhnApache.

Workflow is: Client -> Apache:Broker -> Squid -> Apache:Redirect -> Satellite

Broker handler get request from clients from outside. Some request (POST and HEAD) bypass cache so, it is passed directly to parent. For everything else we transform destination to localhost:80 (which is handled by Redirect handler) and set proxy as local squid. This way we got all request cached localy by squid.

Method Details [hide private]

__init__(self, req)
(Constructor)

source code 

init with http request object

Overrides: rhnShared.SharedHandler.__init__
(inherited documentation)

_initConnectionVariables(self, req)

source code  
set connection variables
NOTE: self.{caChain,rhnParent,httpProxy*} are initialized
      in SharedHandler

rules:
    - GET requests:
          . are non-SSLed (potentially SSLed by the redirect)
          . use the local cache
          . CFG.HTTP_PROXY or CFG.USE_SSL:
              . use the SSL Redirect
                (i.e., parent is now 127.0.0.1)
              . NOTE: the reason we use the SSL Redirect if we
                      are going through an outside HTTP_PROXY:
                      o CFG.HTTP_PROXY is ONLY used by an SSL
                        redirect - maybe should rethink that.
          . not CFG.USE_SSL and not CFG.HTTP_PROXY:
              . bypass the SSL Redirect (performance)
    - POST and HEAD requests (not GET) bypass both the local cache
           and SSL redirect (we SSL it directly)

_prepHandler(self)

source code 

prep handler and check PROXY_AUTH's expiration.

Overrides: rhnShared.SharedHandler._prepHandler

_split_ks_url(req)
Static Method

source code  
read kickstart options from incoming url
URIs we care about look something like:
/ks/dist/session/2xfe7113bc89f359001280dee1f4a020bc/
    ks-rhel-x86_64-server-6-6.5/Packages/rhnsd-4.9.3-2.el6.x86_64.rpm
/ks/dist/ks-rhel-x86_64-server-6-6.5/Packages/
    rhnsd-4.9.3-2.el6.x86_64.rpm
/ks/dist/org/1/ks-rhel-x86_64-server-6-6.5/Packages/
    rhnsd-4.9.3-2.el6.x86_64.rpm

    rhnsd-4.9.3-2.el6.x86_64.rpm

__local_GET_handler(self, req)

source code
