Remove values in the payload

Hello, JRahm Thanks again for your reponse, you are so warm hearted.

I didn't find the way your created stream.

ltm profile stream pantest_stream {
    app-service none
    chunking enabled
    defaults-from stream
    target @<pan>(.*\?)<\\/pan>@@
}

I've tried my side with graphic configuration stream as below:

source I put '<pan>(.*\?)<\\/pan>', and nothing for target. chunk deactivated.

and then activate this stream profile dans virtuel server like this:

After that I checked the data receieved on the server side, it doesn't change anything. There is still 'pan'. Do I miss anything?

PS: 'plainPanRemoved' is done by our app to remove sensitive data.

I also tried with iRules,  the back-end throws directly 'Error reading XMLStreamReader'.

when HTTP_REQUEST {
	# Verify Content-length, POST, URI
    if { [HTTP::header exists Content-length] and [HTTP::method] equals "POST" and [string tolower [HTTP::uri]] contains "/endPointName"}{
	
		# Verify if the request is CreateWalletReq 
		if { [HTTP::payload] contains "<CreateWalletReq"} {        
		
	   # Remove PAN
            STREAM::expression {@<pan>(.*\?)<\\/pan>@@}
	    STREAM::enable

		}
	}
}


when HTTP_RESPONSE {
    STREAM::disable
}

Thanks again.
