Hi,
i am working with HTTP nodes to deal with Webservice invocation.

While configuring HTTPRequest node ,found that , 100s of services are deployed in a machine like,

http://localhost:8082/Addproj/services/AddClass
http://localhost:8082/Addproj/services/SubClass
http://localhost:8082/Addproj/services/MulClass
http://localhost:8082/Addproj/services/RetClass
.....
etc

My query is Can i use one HTTPRequst node for all these Services if yes how?or i should use seperate HTTPRequest node ?
Can anything like http://localhost:8082/Addproj/services/*, use in URL selector?


My aim is to optimise the Message Flow.

My flow looks like

HTTPInputnode->HTTPREquestnode->HTTPReplynode



regards,
Tony

You can't use a single node to invoke all of those services in one request.

You can use a single node to invoke each of those services, one request at a time.

Can you elaborate it ?
Are you talking about one TCP request ?
I'm not sure if I understand you correctly.

It's not possible to make an HTTP Request to more than one URL.
(regardless of what network protocol HTTP is being made over, TCP or etc.)

So one can make an HTTP request to that URL, but it will not be mapped to anything other than "*" as a literal, not "*" as a replacement value.

Exactly.

The best option here is to use one HTTP Request node and code ESQL to request all these URLs (Every URL is one HTTP request).
