commit b2ef1929890d6b372b1c0d1b650a7cc978056ab6 Author: Guillaume Nodet <[email protected]> AuthorDate: Mon Mar 9 11:04:57 2026 +0100 CAMEL-23072: Handle Expect 100-continue on AS2 server side Wrap the request handler with BasicHttpServerExpectationDecorator in AS2ServerConnection. This properly handles clients sending Expect: 100-continue by responding with 100 Continue before the client transmits the request body.
