Problem(Abstract) |
The description for configuring multiple proxy instances
in the "Caching Proxy Administration Guide" topic is not accurate. This
document omits the fact that you must run multiple instances of Caching
Proxy on different IP or alias address and port pairs. |

|
Resolving the
problem |
To support multiple Caching Proxy instances, each binding
IP address and listening port pair (HostName/IP, PORT) must be unique. You
must enable the BindSpecific directive in the configuration
files.
Additionally, when multiple instances of the proxy are running on a single
system, you must define the following directives for each proxy instance:
- *Port: The listening ports for each proxy instance.
- HostName: The binding IP address for each proxy instance. If
the HostName directive is not defined in the configuration file, the proxy
binds to all of the available IP addresses.
- ServerRoot: The home directory for each proxy instance.
- PidFile: The process ID file for each proxy instance. This
directive applies to Linux and UNIX® operating systems only.
- The log file directives: The logging files location for each proxy
instance. (Log, LogArchive, LogFileFormat, LogToGUI,
LogToSyslog.)
