kweb:

• Fast, simple, single-file python2 web-framework/HTTP-server.
• outcome of several years of thoughts/experiments/experience.

why:

• make simple things easy, and complicated things possible.
  1. download kweb9.py
  2. run:

python kweb9.py

3. open URL http://localhost:8010/ from local-browser or http://<ip-address>:8010/ from remote-browser

features:

fast:

• over 2000/dynamic-requests-per-second on a core-i3 laptop !-)

simple:

• zero configuration - file-system and python modules do the needful
• developing dynamic web pages is very easy, look at samples/hello.kweb
• file-system-path-module discovery
• modules are python files in URL-path with .kweb extension when ordinary-files are found, they are sent as-is to the client/browser when .kweb file is found, it is executed and those results sent-back to the client/browser
• the HTTP method is mapped to the module method and called with a request parameter method-name is HTTP request-line method (GET/POST/HEAD/PUT/DELETE...) method returns None - causes path-modules to be executed method returns anything-else returns data back to client/browser
• path-index-module: when request URL is a directory, index.kweb module is used, if it exists. index.kweb can act as a filter to request processing
• single-site-module: serve an entire web-site from a single-python module
• catchall-module: serve all sites from a single python module

secure:

• in *nix: run as the owner of app/hostdir/module per-host/module permissions (run-as - set uid/gid)

cross-platform:

• should work wheverever python works

misc:

• save bandwidth with resume-file-download via. range-support
• virtual-host support
• not all features are documented: python programmers can "easily" figure them out, when the need arises
