Webcache Redirection and VLANs
The Webcache Redirection facility on the Switch 4924 will work on any
VLAN. However, the Webcache Redirection feature on the Switch 4400
only works on the default VLAN.
Redirection on the Cache Port (49XX)
When Webcache Redirection is enabled on the Switch 4924, there will be
no redirection of traffic from the cache port. The diagram below
illustrates this.
Since no web traffic from the cache port of the 49XX will be redirected to
the Webcache (Bullseye), then any web traffic generated by Snoopy will
not be redirected.
Webcache Software Releases
Version 1.0 of the Webcache agent supports only two caching modes
■
proxyMode(1)
■
transparentMode(2)
however, subsequent agent releases support a third caching mode
■
transparentInlineMode(3)
To ensure the Webcache Redirection feature operates alongside these
subsequent agent releases without error, no
Webcache Redirection
Misconfigurations and Optimizations
reports will be generated if the
Webcache is operating in this new third mode.
Restarting Webcache Traffic Server
Once the Webcache mode has been changed it is necessary to shutdown
and restart the Traffic Server process running on the Webcache. This is
performed as part of the
ëEnable Webcache Redirectioní
hyperlink and as
part of the
ëChange
mode to
transparentí
hyperlink, however the
shutdown and restart of this process takes approximately 20 seconds to
complete. Therefore 3Com Network Director does not wait for successful
completion of this stage before responding to the client.
