ProFTPD module mod_memcache

## ProFTPD module `mod_memcache`

The `mod_memcache` module enables ProFTPD support for caching data in memcached servers, using the libmemcached client library. Note that `libmemcached` version 0.41 or later is required.

## Directives

- MemcacheEngine
- MemcacheLog
- MemcacheOptions
- MemcacheReplicas
- MemcacheServers
- MemcacheTimeouts

## MemcacheEngine

Syntax: MemcacheEngine on|off
Default: MemcacheEngine off
Context: "server config", `<VirtualHost>`, `<Global>`
Module: mod_memcache
Compatibility: 1.3.4rc2 and later

The `MemcacheEngine` directive enables or disables the `mod_memcache` module, and thus the configuration of memcache support for the `proftpd` daemon.

## MemcacheLog

Syntax: MemcacheLog path|"none"
Default: None
Context: "server config", `<VirtualHost>`, `<Global>`
Module: mod_memcache
Compatibility: 1.3.4rc2 and later

The `MemcacheLog` directive is used to specify a log file for `mod_memcache`'s reporting on a per-server basis. The file parameter given must be the full path to the file to use for logging.

Note that this path must not be to a world-writable directory and, unless `AllowLogSymlinks` is explicitly set to on (generally a bad idea), the path must not be a symbolic link.

## MemcacheOptions

Syntax: MemcacheOptions opt1 ... optN
Default: None
Context: "server config", `<VirtualHost>`, `<Global>`
Module: mod_memcache
Compatibility: 1.3.4rc2 and later

The currently supported `MemcacheOptions` are:

- `NoBinaryProtocol`

## MemcacheReplicas

Syntax: MemcacheReplicas count
Default: None
Context: "server config", `<VirtualHost>`, `<Global>`
Module: mod_memcache
Compatibility: 1.3.4rc2 and later

Experimental feature

## MemcacheServers

Syntax: MemcacheServers servers
Default: None
Context: "server config", `<VirtualHost>`, `<Global>`
Module: mod_memcache
Compatibility: 1.3.4rc2 and later

The `MemcacheServers` directive is used to configure the IP addresses/ports of the `memcached` servers that the `mod_memcache` module is to use. The list of servers is expressed as a space-delimited list. For example:

      MemcacheServers 1.2.3.4:11211 1.2.3.5:22422

Alternatively, you can configure a Unix domain socket path using e.g.:

      MemcacheServers /var/run/memcached.sock

## MemcacheTimeouts

Syntax: MemcacheTimeouts connect read write
Default: None
Context: "server config", `<VirtualHost>`, `<Global>`
Module: mod_memcache
Compatibility: 1.3.4rc2 and later

Experimental feature

## Installation

The `mod_memcache` module is distributed with ProFTPD. To enable support and use of the memcache protocol in your `proftpd` daemon, use the `--enable-memcache` configure option:

      # ./configure --enable-memcache ...
      # make
      # make install

This option causes the `mod_memcache` module to be compiled into `proftpd`.

You may also need to tell `configure` how to find the `libmemcached` header and library files:

      # ./configure --enable-memcache \
        --with-includes=/path/to/libmemcached/include \
        --with-libraries=/path/to/libmemcached/lib
