+SeaSocks - A tiny embeddable C++ HTTP and WebSocket server
+==========================================================
+
+[](https://travis-ci.org/mattgodbolt/seasocks)
+
+Features
+--------
+* Simple C++ API
+* Serves static content from disk
+* API for building WebSocket servers
+* Simple command line binary for quick serving of static files only
+* Supports newer Hybi-10 and Hybi-16 WebSockets as well as the older Hixie style.
+
+Stuff it doesn't do
+-------------------
+It's not nearly as configurable as Apache, Lighttpd, Nginx, Jetty, etc.
+It provides only very limited support for custom content generation (e.g. Servlets).
+It has been optimized for WebSocket based control.
+
+Getting started
+---------------
+Check out the [tutorial](https://github.com/mattgodbolt/seasocks/wiki/SeaSocks-quick-tutorial) on the wiki.
+
+See [src/app/c/ws_test.cpp](https://github.com/mattgodbolt/seasocks/blob/master/src/app/c/ws_test.cpp) for an example.

+General list of things todo
+---------------------------
+
+* git grep 'TODO' and fix
+* include what you use: lots of headers rely on ambient includes
+* add more tests
+* move more things over to the Request/Response way of doing things
+* Double check it's ok to remove hixie, and do so. Currently no way of testing it anyway
+ (with reference to http://en.wikipedia.org/wiki/WebSocket#Browser_support it's been dead
+ since before Chrome 14)
+
+Further out things
+------------------
+* Generalise the request/response so that persistent connections can be phrased
+ as them.
+* Benchmark and add benchmarks to the tests.

+# SYNOPSIS
+#
+# AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional])
+#
+# DESCRIPTION
+#
+# Check for baseline language coverage in the compiler for the C++11
+# standard; if necessary, add switches to CXXFLAGS to enable support.
+#
+# The first argument, if specified, indicates whether you insist on an
+# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
+# -std=c++11). If neither is specified, you get whatever works, with
+# preference for an extended mode.
+#
+# The second argument, if specified 'mandatory' or if left unspecified,
+# indicates that baseline C++11 support is required and that the macro
+# should error out if no mode with that support is found. If specified
+# 'optional', then configuration proceeds regardless, after defining
+# HAVE_CXX11 if and only if a supporting mode is found.

+/*
+ Independent implementation of MD5 (RFC 1321).
+
+ This code implements the MD5 Algorithm defined in RFC 1321, whose
+ text is available at
+ http://www.ietf.org/rfc/rfc1321.txt
+ The code is derived from the text of the RFC, including the test suite
+ (section A.5) but excluding the rest of Appendix A. It does not include
+ any code or documentation that is identified in the RFC as being
+ copyrighted.
+
+ The original and principal author of md5.c is L. Peter Deutsch
+ <ghost@aladdin.com>. Other authors are noted in the change history
+ that follows (in reverse chronological order):
+
+ 2002-04-13 lpd Clarified derivation from RFC 1321; now handles byte order
+ either statically or dynamically; added missing #include <string.h>
+ in library.
+ 2002-03-11 lpd Corrected argument list for main(), and added int return
+ type, in test program and T value program.
+ 2002-02-21 lpd Added missing #include <stdio.h> in test program.
+ 2000-07-03 lpd Patched to eliminate warnings about "constant is
+ unsigned in ANSI C, signed in traditional"; made test program
+ self-checking.
+ 1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
+ 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5).
+ 1999-05-03 lpd Original version.

+ The code is derived from the text of the RFC, including the test suite

+ The original and principal author of md5.h is L. Peter Deutsch

+ that follows (in reverse chronological order):
+
+ 2002-04-13 lpd Removed support for non-ANSI compilers; removed
+ references to Ghostscript; clarified derivation from RFC 1321;
+ now handles byte order either statically or dynamically.
+ 1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
+ 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
+ added conditionalization for C++ compilation from Martin
+ Purschke <purschke@bnl.gov>.
+ 1999-05-03 lpd Original version.

+ * Description:
+ * This class implements the Secure Hashing Standard as defined
+ * in FIPS PUB 180-1 published April 17, 1995.
+ *
+ * The Secure Hashing Standard, which uses the Secure Hashing
+ * Algorithm (SHA), produces a 160-bit message digest for a
+ * given data stream. In theory, it is highly improbable that
+ * two messages will produce the same message digest. Therefore,
+ * this algorithm can serve as a means of providing a "fingerprint"
+ * for a message.
+ *
+ * Portability Issues:
+ * SHA-1 is defined in terms of 32-bit "words". This code was
+ * written with the expectation that the processor has at least
+ * a 32-bit machine word size. If the machine word size is larger,
+ * the code should still function properly. One caveat to that
+ * is that the input functions taking characters and character arrays
+ * assume that only 8 bits of information are stored in each character.
+ *
+ * Caveats:
+ * SHA-1 is designed to work with messages less than 2^64 bits long.
+ * Although SHA-1 allows a message digest to be generated for
+ * messages of any number of bits less than 2^64, this implementation
+ * only works with messages with a length that is a multiple of 8
+ * bits.
