+ <p>The following calls use the default client profile.
+ Use the proxy <c>"www-proxy.mycompany.com:8000"</c>,
+ except from requests to localhost. This applies to all the
+ following requests.</p>
+ <p>Example:</p>
<code type="erl">
2 > httpc:set_options([{proxy, {{"www-proxy.mycompany.com", 8000},
["localhost"]}}]).
- ok

+ ok</code>
+ <p>The following is an ordinary synchronous request:</p>
<code type="erl">
3 > {ok, {{Version, 200, ReasonPhrase}, Headers, Body}} =
- httpc:request(get, {"http://www.erlang.org", []}, [], []).
- </code>
- <p>With all default values, as above, a get request can also be written
- like this.</p>

+ <p>With all the default values presented, a get request can also be written

<code type="erl">

<code type="erl">

- <p>In this case the calling process is the shell, so we receive the

+ httpc:request(get, {"http://www.erlang.org", []}, [], [{sync, false}]).</code>

+ <c>{http, {ReqestId, Result}}</c>.</p>
+ <p>In this case, the calling process is the shell, so the following
