webMethods Knowlegebase : GZIP compression (1776165)

Problem

We want to enable gzip compression for using in case of large responses from ESB web services.

I tried the following steps (separated & together), but it still doesn't work in IS:

1. In a flow using

a. pub.flow:setResponse2

i. responseBytes – gzipped byte array

ii. contentType - "gzip"

b. pub.flow:setResponseHeader,

i. Content-Encoding

ii. Gzip

2. In a custom response handler

a. Try to build custom java methods that compress SOAPMessage

b.Set Content-Encoding:gzip

3. In TOMCAT add configuration file (from "compression="...."):

<Connector SSLEnabled="true" acceptCount="100" algorithm="SunX509" clientAuth="false" description="Default CTP HTTPS Connector" disableUploadTimeout="true" enableLookups="false" keystoreFile="C:\SoftwareAG\profiles\IS_default\configuration\tomcat\conf\localhost_dont_use_in_production.jks" keystorePass="change_this_password" keystoreType="JKS" maxHttpHeaderSize="8192" maxSpareThreads="75" maxThreads="150" minSpareThreads="25" port="8074" scheme="https" secure="true" server="SoftwareAG-Runtime" sslProtocol="TLS" compression="on" compressionMinSize="2048" compressableMimeType="text/html,text/xml" />

Probably I still miss something.

It's supposed to be easy, built-in and basic functionality.
