Usage

File name	Description	Comments
read_multipart_response.p	Illustrates reading the parts in a multipart message	To run this example, you will need to change the request URI to a real server. You can use the instructions for a webhandler to set up a PASOE instance to do so.
create_mtom_request.p	Illustrates making a MTOM request thru SOAP.	This exemplifies making a SOAP request to post a MTOM (Message Transmission Optimization Mechanism) request using the HttpClient (since this is not supported in native ABL SOAP Client).
create_multipart_form_data.p	Illustrates a HTTP request that sends MultiPart Form data	This example demonstrates creating a MultiPartEntity and adding a boundary and parts to it.
multipart_img_json_txt.p	Illustrates creating a HTTP request that sends MultiPart data including an image	Demonstrates sending an image to a service in a multi-part message.
