The User-Agent header has not been forbidden since Firefox 43 (see https://developer.mozilla.org/en-US/docs/Glossary/Forbidden_header_name).
> Note: The User-Agent header is no longer forbidden, as per spec — see forbidden header name list (this was implemented in Firefox 43) — it can now be set in a Fetch Headers object, or via XHR setRequestHeader().
I've had success setting it in Firefox and Edge for `fetch` and it should work for XMLHttpRequest as well but I'm too lazy to look up how to use XMLHttpRequest. I haven't had any luck setting User-Agent it in Chrome yet - may be a Chrome bug - but I'm not seeing any warnings in the terminal when I use it either, so I don't think allowing it will cause any spurious warnings.
Passing an array as a header value now works as in node.
Header handling with multiple values for the same header is also
tested, and mime type test updated for safari 10.1
Fixes#73
Instead of only permitting bodies on certain methods, only
prohibit them when the browser would give an error (with fetch)
or ignore them (with XHR). This allows bodies with custom
methods and is closer to the behavior of http in node.
Fixes#69
Errors that occur while reading from the ReadableStream that is returned as part of a `fetch` request were not handled. This change propagates these errors up to the `ClientRequest`.
This fixes some more edge cases when converting from a Buffer to
an ArrayBuffer.
Additionally, compared v2.0.5, this avoids an unnecessary copy
when sending data in a request body.
Unforunately some browsers use a version of Buffer
that isn't based on a Uint8Array. Add logic to convert
when necessary but not make copies when unnecessary.
When using the fetch api, exceptions thrown inside
ClientRequest._onFinish, which also calls the user callback,
were being caught and turned into 'error' events. This is
not the correct behavior; these exceptions should remain
uncaught to let the browser print them to the console.
From now on, IE8 is only supported if polyfills for `Object.keys`,
`Array.prototype.forEach`, and `Array.prototype.indexOf` are
provided. The suggested polyfills from MDN are provided in
ie8-polyfill.js, or you can use https://github.com/es-shims/es5-shim
for a more complete set of polyfills.
Make options handling logic match node's `http` module more
closely and let the browser handle all of the relative url
cases itself.
This has a few important advantages:
* Behavior is closer to native `http` modula
* Relative paths in urls are handled properly (fixes#16)
* Code is simpler and more obviously correct
The default behavior now preserves the 'content-type' header, at
the expense of not providing pseudo-streming in Safari, generic
WebKit, and older Chrome. Applications that require streaming
and already use 'prefer-stream' mode will not be affected.
The 'prefer-fast' mode is now deprecated, as that behavior now
matches the default. The 'allow-wrong-content-type' mode is new;
it gives the same behavior as the old default in case binary
streaming is essential.
Fixes#8
In order to have parity with XMLHttpRequest fetch credentials should use same-origin instead of omit
Setting XMLHttpRequest.withCredentials to false has no effect on same-site request
