The web service client has to set in the request following HTTP header

Accept-Encoding: gzip

I have posted this already.

Hi Stefan,

In Sender SOAP adapter configuration,

in module tab page , i have given these entries.even then i am not able to see any kind of compression..

I am not talking about the SOAP adapter configuration, but about the web service client.

The web service client has to request the compression.

My scenario is SOAP--XI--BAPI(R/3 system)

I have configured SOAP sender communication channel and in the module tab i have given the required parameters for the gzip compression.

in j2ee serevr i have set the following settings:

?MinimumGZipLength? property value as 1024 Bytes

AlwaysCompressed? property value = null

?NeverCompressed? property value = null

?CompressedOthers? property value as ?true?

MaximumCompressedURLLength = -1

i am using on my machine HTTPAnalyzerV3 s/w to analyse the compression.But i am not seeing any compression in my response mesage.but if i open any other website like google its showing compression in that tool.

do i need to analyse by this tool on server machine ?

i am not clear what to do now?

Does the web service client request the compression with the HTTP header parameter:

Accept-Encoding: gzip

?

In the "module" tab of the SOAP adapter channel, you can add following parameter to the XISOAPAdapterbean:

XMBWS.Encoding gzip

See details in this guide:

You can check with the TCPGateway or similar tools:

You need not care about the incoming message in PI, as the SOAP adapter does the unzipping by its own. The parameter is only necessary for the outgoing message, that means the request for receiver, the response for the sender adapter.
