I've been using the HTTP connector in multipart form mode for some time to POST data to an applications RESTful API.

Recently I've been having trouble posting some sequence sets - I get a 'socket-error' message. I've narrowed the issue down to the size of the individual files being posted. Any file >212KB causes the process to fail. What I don't know is if this is a limit imposed by the HTTP Connector Component or the server receiving the package.

or, since in either case the size limit seems unfeasibly low perhaps there's something more than can be done in the configuration of the HTTP Connector component? In the help text of the Additional Parameter parameters it eludes to using metadata to "associate a filename with the parameter". This help text in this regard is not as complete as I'm used to seeing throughout the product - it speaks of defining metadata values on the parameter but which parameter? Options: Parameter x / Parameter x Name / Parameter x Value? And for filename does it require the full filepath, can it accept tokenization? If the filename is referenced as the metadata value then what should be the content of the Parameter x Value parameter?

Up to this point I've been reading content into a property on the data record and this property is referenced in the HTTP Connector Parameter x Value parameter. Would using the metadata technique be more suitable for my purposes perhaps?

Thanks for any help,

Regards,
