New Module MemCached

Courtesy of Henning Westerholt, a new module was added to the repository - 'memcached'. It allows to connect to a memcached server and supports following operations:

  • add key
  • get key
  • delete key
  • atomic operations

The operations can be done directly in the configuration file via pseudo-variables.

Further details can be found in the module documentation:

Memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic applications by alleviating database load.

  • access in config file to both request or reply during transaction processing
  • perl-like regular expression support (PCRE library)
