HTTP Configuration Directives
| Home | Agenda |
  • HTTP Configuration Directives are statements that instruct the HTTP server about the services it should provide.
  • HTTP configuration directives are members of file QATMHTTPC in library QUSRSYS.
  • HTTP configuration directives are maintained
    • explicitly through command wrkhttpcfg
    • impliciyly through the HTTP server Admin
  • The reference manual for HTTP directives is
    SC41-5434 HTTP Server for AS/400 Webmaster's Guide

Generating HTTP Configuration Directives for your Web pages

 Assume the following:
  • you want to develop some CGI programs
  • the library containing your CGI programs and source file HTMLSRC (dynamic html texts) is named mylib
  • the IFS root directory containing images (pc files extension .gif and .jpg) and, if you wish, html static pages (pc files extension .htm) is /mylib
If you sign on a 5250 screen as QSECOFR and you enter command
          cgidev2/setcgilib mylib
you'll get a screen asking whether you want HTTP directives generated for you.
If you reply Y (for Yes), the following directives are generated:
Map /mylibh/* /QSYS.LIB/MYLIB.LIB/HTMLSRC.FILE/*
Pass /QSYS.LIB/MYLIB.LIB/HTMLSRC.FILE/*
Pass /mylib/*
Exec /mylibp/* /QSYS.LIB/MYLIB.LIB/* %%EBCDIC%%
Let us comment the above directives:
  • Map /mylibh/* /QSYS.LIB/MYLIB.LIB/HTMLSRC.FILE/*
     This directive instructs the server that any time it meets a URL request containing /mylibh/
    (* = whatever is attached to it), it should translate it to /QSYS.LIB/MYLIB.LIB/HTMLSRC.FILE/
    and attach whatever was attached to the first sentence.
    In other words, the Map directive is a nice way to allow short names in your html to be interpreted in their full meanings by your http server.
  • Pass /QSYS.LIB/MYLIB.LIB/HTMLSRC.FILE/*
     This directive instructs the server to accept requests to access members of file htmlsrc in library mylib.
  • Pass /mylib/*
     This directive instructs the server to accept requests to access whatever file in root directory /mylib.
  • Exec /mylibp/* /QSYS.LIB/MYLIB.LIB/* %%EBCDIC%%
     This directive instructs the server to accept requests to run CGI programs in library mylib.
      The %%EBCDIC%% value overrides the value specified on the CGIConvMode directive (which defaults to %%MIXED%%).
    CGIConvMode instructs the HTTP about the conversion rule to be used to pass the environment variables (including the QUERY_STRING, that is the input data from the browser) to a CGI.
    %%EBCDIC%% is mandatory to correctly operate procedure zhbGetInput, and is compatible with procedure getInput.
    In your html, the request to run program (say) mycgi1 in library mylib should be written as
              /mylibp/mycgi1.pgm
