Closes #12775
Calling
request.getInputStream()causes an attempt to write a100 Continueto the response: if the request did not contain theExpect 100header, we create an exception and then ignore it.This PR only attempts to write the
100 Continueiff the request has anExpect 100header, thus saving the cpu cycles involved in creating the useless exception with stack traces etc.
