wso2 - Is there a way to turn on global payload compression (gzip) on the ESB or API Manager? -

is there way switch on payload compression on either esb (< 5.0.0) or api manager (< 2.0.0) , application/json content-type ?

i have achieved on resource level global option ideal.

after research have found following available option in catalina-server.xml :

compression="on" & compressablemimetype.

this not tomcat servers web interface , not services , axis2 for.

after more digging found archived article http://wso2.com/library/3316/. inside references following :

"mc_gzip_response (server, writable) : default http response body not compressed. set message context property true have response body gzip compressed."

sounds need , not sure set parameter.

thanks "ycr". set me on right path.

what did achieve create global custom insequence , outsequence (global extensions) api's deployed inside api manager , mentioned in https://docs.wso2.com/display/am1100/adding+mediation+extensions.

the insequence checks value/existence of accept-encoding header of request , outsequence gzips response accordingly.

steps:

create "insequence" handler xml file:

<sequence xmlns="http://ws.apache.org/ns/synapse" name="wso2am--ext--in"> <property name="encoding" expression="$trp:accept-encoding"/> <filter xpath="fn:contains(fn:lower-case(get-property('encoding')) , 'gzip')">     <then>         <property name="compression" value="true"/>     </then>     <else>         <property name="compression" value="false"/>     </else> </filter> 

the file name can name inside tag needs wso2am--ext--in

similarly create "outsequence" file :

<sequence xmlns="http://ws.apache.org/ns/synapse" name="wso2am--ext--out"> <filter source="get-property('compression')" regex="true">     <then>         <property action="remove" name="transport_headers" scope="axis2"/>         <property name="content-encoding" scope="transport" type="string" value="gzip"/>         <property name="transfer-encoding" scope="transport" type="string" value="gzip"/>     </then>     <else>         <property name="transport_headers" action="remove" scope="axis2"/>     </else> </filter> 

copy files inside /repository/deployment/server/synapse-configs/default/sequences directory. hot-deployed.

send request deployed api header accept-encoding set gzip (any string gzip in compressed) , should respond content-encoding: gzip
