+# Passing data through stdin cannot be combined with data fields specified
+# on the command line:
+echo 'data' | http POST example.org more=data   # This is invalid
+
+
+# AN ALTERNATIVE TO REDIRECTED stdin is specifying a filename (as
+# @/path/to/file) whose content is used as if it came from stdin.
+
+# It has the advantage that THE Content-Type HEADER IS AUTOMATICALLY SET
+# to the appropriate value based on the filename extension. For example,
+# the following request sends the verbatim contents of that XML file with
+# Content-Type: application/xml:
+http PUT httpbin.org/put @/data/file.xml
+
+# Download a file:
+http example.org/Movie.mov > Movie.mov
+
+# Download an image of Octocat, resize it using ImageMagick, upload it
+# elsewhere:
+http octodex.github.com/images/original.jpg | convert - -resize 25% -  | http example.org/Octocats

+# response in less pager:
+http --pretty=all --verbose example.org | less -R

+# When enabled using the --download, -d flag, response headers are printed
+# to the terminal (stderr), and a progress bar is shown while the response
+# body is being saved to a file.
+http --download https://github.com/jkbrzt/httpie/tarball/master
+
+# You can also redirect the response body to another program while the
+# response headers and progress are still shown in the terminal:
+http -d https://github.com/jkbrzt/httpie/tarball/master |  tar zxf -
+
+# If --output, -o is specified, you can resume a partial download using
+# the --continue, -c option. This only works with servers that support
+# Range requests and 206 Partial Content responses. If the server doesn't
+# support that, the whole file will simply be downloaded:
+http -dco file.zip example.org/file
+
+# Prettified streamed response:
+http --stream -f -a YOUR-TWITTER-NAME https://stream.twitter.com/1/statuses/filter.json track='Justin Bieber'
+
+# Send each new tweet (JSON object) mentioning "Apple" to another
+# server as soon as it arrives from the Twitter streaming API:
+http --stream -f -a YOUR-TWITTER-NAME https://stream.twitter.com/1/statuses/filter.json track=Apple | while read tweet; do echo "$tweet" | http POST example.org/tweets ; done
+
+# Create a new session named user1 for example.org:
+http --session=user1 -a user1:password example.org X-Foo:Bar
+
+# Now you can refer to the session by its name, and the previously used

+http --session=user1 example.org
+
+# To create or reuse a different session, simple specify a different name:
+http --session=user2 -a user2:password example.org X-Bar:Foo
+
+# Instead of a name, you can also directly specify a path to a session
+# file. This allows for sessions to be re-used across multiple hosts:
