Posting .zip files over https

We have a customer requirement where they will be posting multiple zip files over https.

Can anyone please let us know if it is possible to post zip files over https

If yes, once the files have been received in webMethods then how do we recognize them and carry out further processing

Yes it is possible to recieve zip files through https. There is no built in services available in webmethods to process compressed files, however you can write custom java service with Java API for processing compressed files.
