HTTP Receiver Adapter capable of posting.CSV files as output payload?

Dear Expert,

I am working on File to HTTP adapter(pass through) scenario  where i need to  pick the .csv files from shared directory and post target system using HTTP adapter . As far as i know HTTP adapter simply post files no matter which format it was.  I  can see one parameter Content type in HTTP receiver adapter comm channel configuration by default it was text/xml , if  i mention as CSV will my scenario work? . My client is not ready to go with (SOAP, FILE adapter usage). This is the only option i have go with HTTP adapter.

Parameters from the Communication Channel for Technical Routing

●      Content type (the entry text/XML is expected as default)

Specifies the content format  (payload) that the message should have.

●      (Optional) header fields for the receiver-specific protocol
