Preface
What is Apache Traffic Server?
Apache Traffic Server™ is a high-performance web proxy cache that improves network efficiency and performance by caching frequently-accessed information at the edge of the network. This brings content physically closer to end users, while enabling faster delivery and reduced bandwidth use. Traffic Server is designed to improve content delivery for enterprises, Internet service providers (ISPs), backbone providers, and large intranets by maximizing existing and available bandwidth.
This manual will explore every aspect of installing, managing, extending, and troubleshooting Traffic Server.
Typographic Conventions
This documentation uses the following typographic conventions:
- Italic
Used to introduce new terms on their initial appearance.
- Example:
The Apache Traffic Server™ object storage is based on a cyclone buffer architecture. Cyclone buffers are a form of storage addressing in which a single writer continually reclaims the oldest allocations for use by new updates.
- Monospace
Represents C/C++ language statements, commands, file paths, file content, and computer output.
- Example:
The default installation prefix for Traffic Server is
/usr/local/ts.
- Bracketed Monospace
Represents variables for which you should substitute a value in file content or commands.
- Example:
Running the command
traffic_ctl metric get <name>will display the current value of a performance statistic, where<name>is the statistic whose value you wish to view.
- Ellipsis
Indicates the omission of irrelevant or unimportant information.
