.SH DESCRIPTION
.IX Header "DESCRIPTION"
Mojo::UserAgent is a full featured non-blocking I/O HTTP and WebSocket user agent, with IPv6, TLS, SNI, IDNA,
HTTP/SOCKS5 proxy, UNIX domain socket, Comet (long polling), Promises/A+, keep-alive, connection pooling, timeout,
cookie, multipart, gzip compression and multiple event loop support.
.PP
All connections will be reset automatically if a new process has been forked, this allows multiple processes to share
the same Mojo::UserAgent object safely.
.PP
For better scalability (epoll, kqueue) and to provide non-blocking name resolution, SOCKS5 as well as TLS support, the
optional modules EV (4.32+), Net::DNS::Native (0.15+), IO::Socket::Socks (0.64+) and IO::Socket::SSL
(2.009+) will be used automatically if possible. Individual features can also be disabled with the \f(CW\*(C`MOJO_NO_NNR\*(C'\fR,
\&\f(CW\*(C`MOJO_NO_SOCKS\*(C'\fR and \f(CW\*(C`MOJO_NO_TLS\*(C'\fR environment variables.
.PP
See "USER AGENT" in Mojolicious::Guides::Cookbook for more.
