MediationZone can be configured to route outgoing HTTP traffic through an HTTP proxy. This is commonly required in networking environments where the execution context has limited access to the internet. Proxy configuration has to be performed on every host (Platform or Execution Context (EC)) that is required to route HTTP traffic through a proxy.
Proxy support is available for:
HTTP APL functions
HTTP Batch agent
GCP PubSub Subscriber agent
GCP PubSub Publisher agent
GCP BigQuery agent
HTTP/2 Client agent
Salesforce Streaming agent
This chapter has the following sections:
Configuring Proxy Support
Standard Java system properties are used to configure MediationZone to route HTTP traffic through an HTTP proxy. These properties must be configured at the Execution Context (EC) level for all execution contexts. Refer to proxy properties here: Execution Context .
At least one of these properties has to be set to use HTTP Proxy:
http.proxyHosthttps.proxyHost
It is often necessary to provide a list of destinations that should not be routed through the proxy. This list can be configured using the proxy property http.nonProxyHosts. Note that this property, despite the name, applies to both http and https traffic.
Currently, only HTTP/1.1 has been verified to route through an HTTP proxy.
Authenticating the Proxy
MediationZone supports basic authentication to HTTP proxy. The username and password are configured using system properties. Refer to the proxy properties here: Execution Context.
Example Configuration
Here is an example of how to configure the system properties to use an HTTP Proxy.
Use the following command to edit the system properties.
mzsh topo open ec1
config {
   classpath {}
   jvmargs {
       args=[]
       maxMetaspace=[
           "-XX:MaxMetaspaceSize=196M"
       ]
   }
   properties {
       mz.webserver.xframeoptions=DENY
       pico.groups=""
       ec.backlog.dir="/Users/mzadmin/mz9/mz9HttpProxy/tmp"
       ec.webserver.port=9090
       http.proxyHost=192.168.205.4
       http.proxyPort=3128
       https.proxyHost=192.168.205.4
       https.proxyPort=3128
       http.proxyUser=test
