2.1Server Behaviour
2.2VMS Versions
2.3TCP/IP Packages
2.4International Features

The most fundamental component of the WASD VMS Web Services environment is the HTTP server (HyperText Transport Protocol Daemon, or HTTPd). WASD has a single-process, multi-threaded, asynchronous I/O design.

The following bullet-points summarise the features and facilities, many of which are described in significant detail in following chapters.

2.1Server Behaviour

The technical aspects of server design and behaviour are described in WASD_ROOT:[SRC.HTTPD]READMORE.TXT

2.2VMS Versions

The WASD server is supported on any VMS version from V7.0 upwards, on Alpha, Itanium and x86-64 architectures. The current version (as of 2021), V8.4 Alpha and Itanium, as is commonly the case on VMS platforms, required nothing more than relinking. Obviously no guarantees can be made for yet-to-be-released versions but at a worst-case these should only require the same.

The WASD distribution and package organisation fully supports mixed-architecture clusters (Alpha, Itanium and/or x86-64 in the one cluster) as one integrated installation.

2.3TCP/IP Packages

The WASD server uses the TCP/IP Services (UCX) BG $QIO interface. The following packages support this interface and may be used.

To deploy IPv6 services this package must support IPv6.

2.4International Features

WASD provides a number of features that assist in the support of non-English and multi-language sites. These "international" features only apply to the server, not necessarily to any scripts!
