> Should USE_EXPECT_CONTINUE be false by default?
> -----------------------------------------------
>
> Key: HTTPCLIENT-889
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-889
> Project: HttpComponents HttpClient
> Issue Type: Wish
> Components: HttpClient
> Affects Versions: 4.0 Final
> Reporter: Ren Waldura
> Priority: Minor
> Fix For: 4.1 Alpha1
>
>
> It seems the point of USE_EXPECT_CONTINUE is to improve performance when
> posting large data.
> http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html says:
> << The purpose of the 100 (Continue) status (see section 10.1.1) is to allow
> a client that is sending a request message with a request body to determine
> if the origin server is willing to accept the request (based on the request
> headers) before the client sends the request body. In some cases, it might
> either be inappropriate or highly inefficient for the client to send the body
> if the server will reject the message without looking at the body. >>
> There's nothing wrong with HttpClient performing well by default, however,
> every other HTTP client library I've used does not behave like this (PHP
> curl, Perl LWP). The default is always to do one request, including the body.
> Maybe dumb, but simple.
> It seems to me HttpClient's default behavior should the simplest, most
> compatible with all HTTP-speaking services out there. "100 Continue" is
> somewhat advanced, and may not be correctly implemented by all services.
> (That's of course how I found out about it -- my server doesn't implement it.)
> If USE_EXPECT_CONTINUE is used only for performance reasons, it seems like it
> would be simpler (and therefore maybe more "correct") to have it "off" by
> default. And only enable it when needed, when there is a good reason to.
> Just my thoughts. And a wish. Thanks!
