Hello, 

We have a requirement to do a HTTP Post to AEM (Adobe Experience Manager). 

This service at AEM returns back with the message showing number of parameters and key-value information. (Just an echo for testing).

I am facing a wierd challenge where I posting a file to AEM using HTTP Post multipart form data as in the below code but somehow AEM is not able to identify any parameters being sent within the body.

When we test the same AEM service using Postman it works fine. It replies back with number of parameters and keyvalue pairs that exist in the message body.

I constructed the same multipart message in Salesforce and invoked httppost to AEM, I get null value returned. On taking to AEM team, they mention that message is not being constructed correctly.

So started to sending the Multipart messages to thirdparty clients like postbin, requestbin or beeceptor. They all seem to be fine. I compared this with how postman would send. It looks fine. 

In summary:
Postman to AEM - worksfine

Compared  Postman message and Salesforce multipart message using requestbin. looks good.

But Saesforce to AEM - doesnt work.

Has anybody experienced similar issue? anybody has integrated with AEM?
I am suspecting that it has something to do with charactersets, but I dont know what could be wrong. I am not sending any special characters.
Any suggestions?
