Recently, the Apache Software Foundation released the traffic Server version 5.3.1, which fixes some bugs in previous versions and is compatible with all 5.x versions.

Apache traffic server is a fast, scalable, extensible, http/1.1-compatible cache proxy server. Traffic server was a commercial product that was donated by Yahoo to the Apache Software Foundation and has now become the top project of Apache.

The main features of traffic server are as follows:

• Caching: Improves response time while reducing server load and bandwidth, which is achieved by caching and reusing frequently requested web pages, pictures, and Web service calls.
• Proxy: You can easily add keep-alive, filter content requests, and add load balancing, which is achieved by adding a proxy layer.
• Fast: Good scalability on modern SMP hardware to handle tens of thousands of requests per second.
• Extensible: Provides APIs that you can write your own plug-in to implement any function, from modifying HTTP headers, processing ESI requests, to writing your own caching algorithms.
• Verified by practice: in Yahoo as a forward proxy and reverse proxy can process 400TB of data daily, Apache traffic server has been proven in practice.
• Widely used: At present, there are many companies around the world using traffic Server, ranging from small start-ups to large internet companies such as Yahoo, Linkedin, Comcast, Akamai, cloud storage, easy Fox network and so on.

v5.3.1 is the latest version of the current traffic server, which resolves some issues and fixes some bugs:

• Remove Http2_frame_type_max Enumeration
• Resolves a hpack error
• Fixed the problem of frame type detection under HTTP/2
• SSL handshake read to correctly handle EOF and error conditions
• Fixed a memory leak issue with ssl_multicert.config reload
• Added Openssl_include and openssl_libs to the makefile.am
• Reads "Proxy.config.cache.ram_cache.use_seen_filter" only once and no longer creates callbacks

Interested readers can download the latest version of the trial on the Apache traffic server website.
