Similar to the previous chapter, the first step towards establishing the new architecture will be to discover the appropriate module. The default Nginx build comes with the proxy module, which allows forwarding of HTTP requests from the client to a backend server. We will be configuring multiple aspects of the module:

• Basic address and port information of the backend server
• Caching, buffering, and temporary file options
• Limits, timeout, and error behavior
• Other miscellaneous options

All these options are available via directives which we will learn to configure throughout this section.
