Description
If Apache is in use as a ReverseProxy, it can be used to add additional headers.
Alternately APIX-G can add headers using a transformation or a Full-type Mapping. Using a stylesheet has additional flexibility of setting conditions to look into the NB Request context as well.
Issue/Introduction
This article provides inputs and sample for adding additional headers to the SB HTTP Request.
Environment
All Supported Platforms
Resolution
#viaAPIX By using a Transformation, APIX can add additional headers to the outgoing/southbound request it sends to the Target. Please see attached archive for a sample stylesheets -- this should be configured as a Full-type Mapping and applied as a Request Transform on the Target.
#viaApache Using the "RequestHeader" directives Apache can add headers to outgoing request it forwards to the Target, when setup as ReverseProxy. Here is the one I tested with: ------------ ProxyPass /viaApache/ http://vviswana-hpz2:9222/ ProxyPassReverse /viaApache/ http://vviswana-hpz2:9222/
Also attached is a sample debug enabled log showing the above options in play.
Note: The below command can be used to validate the stylesheet before testing on the engine: java -cp C:/apix233/asg/2.3/lib/asg-functions.jar;C:/apix233/asg/2.3/lib/ext/tpcl/saxon9pe.jar;C:/apix233/asg/2.3/lib/ext/tpcl/json_simple-1.1.jar;C:/apix233/be/5.2/lib/ext/tibco/TIBCOxml.jar;C:/apix233/asg/2.3/lib/ext/tpcl/log4j-1.2.15.jar;C:/apix233/be/5.2/lib/ext/tpcl/apache/commons-lang3-3.3.2.jar;C:/apix233/be/5.2/lib/cep-common.jar;C:/apix233/be/5.2/lib/cep-kernel.jar;C:/apix233/asg/2.3/lib/ext/tpcl/merastring2base64.jar com.tibco.be.functions.xml.XsltTransformer ./
