Altova FlowForce Server 2025 Advanced Edition

Returns the parameter param from the "Content-Type" header of a stream if such header and parameter exists; otherwise, it returns the value of the default argument. This function can be used to receive messages that follow the optional AS2 profile Multiple Attachments (MA). Namely, it can extract the starting document Content-ID and Content-Type specified as parameters 'start' and 'type' to multipart/related content type. It can also be used to extract the character set, as shown in the example below.
