-communication channels over a single TCP connection. *IXWebSocket* is a C++ library for client and server Websocket communication, and for client HTTP communication.

It has been tested on the following platforms.

 ### Large messages
 
-Large frames are broken up into smaller chunks or messages to avoid filling up the os tcp buffers, which is permitted thanks to WebSocket [fragmentation](https://tools.ietf.org/html/rfc6455#section-5.4). Messages up to 500M were sent and received succesfully.
+Large frames are broken up into smaller chunks or messages to avoid filling up the os tcp buffers, which is permitted thanks to WebSocket [fragmentation](https://tools.ietf.org/html/rfc6455#section-5.4). Messages up to 1G were sent and received succesfully.
 
 ## Limitations
 
-* There is no text support for sending data, only the binary protocol is supported. Sending json or text over the binary protocol works well.
+* No utf-8 validation is made when sending TEXT message with sendText()
 * Automatic reconnection works at the TCP socket level, and will detect remote end disconnects. However, if the device/computer network become unreachable (by turning off wifi), it is quite hard to reliably and timely detect it at the socket level using `recv` and `send` error codes. [Here](https://stackoverflow.com/questions/14782143/linux-socket-how-to-detect-disconnected-network-in-a-client-program) is a good discussion on the subject. This behavior is consistent with other runtimes such as node.js. One way to detect a disconnected device with low level C code is to do a name resolution with DNS but this can be expensive. Mobile devices have good and reliable API to do that.
 * The server code is using select to detect incoming data, and creates one OS thread per connection. This is not as scalable as strategies using epoll or kqueue.

+# spdlog
+
+Very fast, header only, C++ logging library. [![Build Status](https://travis-ci.org/gabime/spdlog.svg?branch=master)](https://travis-ci.org/gabime/spdlog)  [![Build status](https://ci.appveyor.com/api/projects/status/d2jnxclg20vd0o50?svg=true)](https://ci.appveyor.com/project/gabime/spdlog)
+
+
+
+## Install
+#### Just copy the headers:
+
+* Copy the source [folder](https://github.com/gabime/spdlog/tree/v1.x/include/spdlog) to your build tree and use a C++11 compiler.
+
+#### Or use your favorite package manager:
+
+* Ubuntu: `apt-get install libspdlog-dev`
+* Homebrew: `brew install spdlog`
+* FreeBSD:  `cd /usr/ports/devel/spdlog/ && make install clean`
+* Fedora: `yum install spdlog`
+* Gentoo: `emerge dev-libs/spdlog`
+* Arch Linux: `yaourt -S spdlog-git`
+* vcpkg: `vcpkg install spdlog`
+ 
+
+## Platforms
+ * Linux, FreeBSD, OpenBSD, Solaris, AIX
+ * Windows (msvc 2013+, cygwin)
+ * macOS (clang 3.5+)
+ * Android
+
+## Features
+* Very fast (see [benchmarks](#benchmarks) below).
+* Headers only, just copy and use.
+* Feature rich formatting, using the excellent [fmt](https://github.com/fmtlib/fmt) library.
+* Fast asynchronous mode (optional)
+* [Custom](https://github.com/gabime/spdlog/wiki/3.-Custom-formatting) formatting.
+* Multi/Single threaded loggers.
+* Various log targets:
+    * Rotating log files.
+    * Daily log files.
+    * Console logging (colors supported).
+    * syslog.
+    * Windows debugger (```OutputDebugString(..)```)
+    * Easily extendable with custom log targets  (just implement a single function in the [sink](include/spdlog/sinks/sink.h) interface).
+* Severity based filtering - threshold levels can be modified in runtime as well as in compile time.
+* Binary data logging.
+
+
+## Benchmarks
+
+Below are some [benchmarks](https://github.com/gabime/spdlog/blob/v1.x/bench/bench.cpp) done in Ubuntu 64 bit, Intel i7-4770 CPU @ 3.40GHz

+
+## Usage samples
+
+#### Basic usage
+```c++
+#include "spdlog/spdlog.h"
+int main() 
+{
+    spdlog::info("Welcome to spdlog!");
+    spdlog::error("Some error message with arg: {}", 1);
+    
+    spdlog::warn("Easy padding in numbers like {:08d}", 12);
+    spdlog::critical("Support for int: {0:d};  hex: {0:x};  oct: {0:o}; bin: {0:b}", 42);
+    spdlog::info("Support for floats {:03.2f}", 1.23456);
+    spdlog::info("Positional args are {1} {0}..", "too", "supported");
+    spdlog::info("{:<30}", "left aligned");
+    
+    spdlog::set_level(spdlog::level::debug); // Set global log level to debug
+    spdlog::debug("This message should be displayed..");    
+    
+    // change log pattern
+    spdlog::set_pattern("[%H:%M:%S %z] [%n] [%^---%L---%$] [thread %t] %v");
+    
+    // Compile time log levels
+    // define SPDLOG_ACTIVE_LEVEL to desired level
+    SPDLOG_TRACE("Some trace message with param {}", {});
+    SPDLOG_DEBUG("Some debug message");
+        
+}
+```
+#### create stdout/stderr logger object
+```c++
+#include "spdlog/spdlog.h"
+#include "spdlog/sinks/stdout_color_sinks.h"
+void stdout_example()
+{
+    // create color multi threaded logger
+    auto console = spdlog::stdout_color_mt("console");    
+    auto err_logger = spdlog::stderr_color_mt("stderr");    
+    spdlog::get("console")->info("loggers can be retrieved from a global registry using the spdlog::get(logger_name)");
+}
+```
+---
+#### Basic file logger
+```c++
+#include "spdlog/sinks/basic_file_sink.h"
+void basic_logfile_example()
+{
+    try 
+    {
+        auto my_logger = spdlog::basic_logger_mt("basic_logger", "logs/basic-log.txt");
+    }
+    catch (const spdlog::spdlog_ex &ex)
+    {
+        std::cout << "Log init failed: " << ex.what() << std::endl;
+    }
+}
+```
+---
+#### Rotating files
+```c++
+#include "spdlog/sinks/rotating_file_sink.h"
+void rotating_example()
+{
+    // Create a file rotating logger with 5mb size max and 3 rotated files
+    auto rotating_logger = spdlog::rotating_logger_mt("some_logger_name", "logs/rotating.txt", 1048576 * 5, 3);
+}
+```
+
+---
+#### Daily files
+```c++
+
+#include "spdlog/sinks/daily_file_sink.h"
+void daily_example()
+{
+    // Create a daily logger - a new file is created every day on 2:30am
+    auto daily_logger = spdlog::daily_logger_mt("daily_logger", "logs/daily.txt", 2, 30);
+}
+
+```
+
+---
+#### Cloning loggers 
+```c++
+// clone a logger and give it new name.
+// Useful for creating subsystem loggers from some "root" logger
+void clone_example()
+{
+    auto network_logger = spdlog::get("root")->clone("network");
+    network_logger->info("Logging network stuff..");
+}
+```
+
+---
+#### Periodic flush
+```c++
+// periodically flush all *registered* loggers every 3 seconds:
+// warning: only use if all your loggers are thread safe!
+spdlog::flush_every(std::chrono::seconds(3));
+
+```
+
+---
+#### Binary logging
+```c++
+// log binary data as hex.
+// many types of std::container<char> types can be used.
+// ranges are supported too.
+// format flags:
+// {:X} - print in uppercase.
+// {:s} - don't separate each byte with space.
+// {:p} - don't print the position on each line start.
+// {:n} - don't split the output to lines.
+
+#include "spdlog/fmt/bin_to_hex.h"
+
+void binary_example()
+{
+    auto console = spdlog::get("console");
+    std::array<char, 80> buf;
+    console->info("Binary example: {}", spdlog::to_hex(buf));
+    console->info("Another binary example:{:n}", spdlog::to_hex(std::begin(buf), std::begin(buf) + 10));
+    // more examples:
+    // logger->info("uppercase: {:X}", spdlog::to_hex(buf));
+    // logger->info("uppercase, no delimiters: {:Xs}", spdlog::to_hex(buf));
+    // logger->info("uppercase, no delimiters, no position info: {:Xsp}", spdlog::to_hex(buf));
+}
+
+```
+
+---
+#### Logger with multi sinks - each with different format and log level
+```c++
+
+// create logger with 2 targets with different log levels and formats.
+// the console will show only warnings or errors, while the file will log all.
+void multi_sink_example()
+{
+    auto console_sink = std::make_shared<spdlog::sinks::stdout_color_sink_mt>();
+    console_sink->set_level(spdlog::level::warn);
+    console_sink->set_pattern("[multi_sink_example] [%^%l%$] %v");
+
+    auto file_sink = std::make_shared<spdlog::sinks::basic_file_sink_mt>("logs/multisink.txt", true);
+    file_sink->set_level(spdlog::level::trace);
+
+    spdlog::logger logger("multi_sink", {console_sink, file_sink});
+    logger.set_level(spdlog::level::debug);
+    logger.warn("this should appear in both console and file");
+    logger.info("this message should not appear in the console, only in the file");
+}
+```
+
+---
+#### Asynchronous logging
+```c++
+#include "spdlog/async.h"
+#include "spdlog/sinks/basic_file_sink.h"
+void async_example()
+{
+    // default thread pool settings can be modified *before* creating the async logger:
+    // spdlog::init_thread_pool(8192, 1); // queue with 8k items and 1 backing thread.
+    auto async_file = spdlog::basic_logger_mt<spdlog::async_factory>("async_file_logger", "logs/async_log.txt");
