Yaws manufacturer description

Yaws 1.98 is a HTTP high perfomance 1.1 webserver particularly well suited for dynamic-content webapplications. Two separate modes of operations are supported.

  • Standalone mode where Yaws Web runs as a regular webserver daemon. This is the default mode.

  • Embedded mode where Yaws download runs as an embedded webserver in another erlang application.

Yaws is entirely written in Erlang furthermore it is a multithreaded webserver where one Erlang light weight process is used to handle each client.
The main advantages of yaws compared to other Web technologies are performance and elegance. The performance comes from the underlying Erlang system and its ability to handle concurrent processes in an efficent way. Its elegance comes from Erlang as well. Web applications dont have to be written in ugly adhoc languages.

What is new in 1.98 changeinfo log

Maintenance release with a long series of fixes mostly from Steve Vinoski./yaws

  • should not not include .yaws files, nor directories "protected" with an index file, nor directories protected by an auth directive. (Hans-Christian Esperer )
  • adjust to R14B change in gen_tcp:recv for {packet,http} mode Where we handle the return value of gen_tcp:recv while reading headers from the socket (such as with calls to yaws:do_recv), handle new R14B return values as well as existing return values for previous releases. (Steve)
  • for portability, use erlang:md5 rather than crypto md5 Since OpenSSL availability on Windows for working with the crypto module is apparently questionable, use the erlang:md5 function in place of the crypto md5 functions. (Steve)

  • several fcgi updates and bugfixes (Steve)
  • Add auth_skip_docroot server config variable (Christian Hennig)
