> We are setting up ESB to be load balanced with IIS and ESB receives following
> and then IIS does not sends anything at all and requests time out.
> Looks like the source of the problems is that IIS sends a HTTP header called
> "Expect: 100-Continue", and ESB's apache http core library does not
> understand that.
> Basically, server suppose to respond to that header, and if not, client does
> not send any more data. Is there any chance you can disable that header?
