    Setting MIME type for CGI output (Web and WAP versions have same extension)


    Sorry if this sounds like a newbie question, but I'm just getting started with WAP... and I'd like to produce my first site with limited resources (a leased "virtual" server and a simple CGI database).

    I'm trying to set up a WAP site which will provide access to a database of concerts, but I'm running into problems with MIME types of the CGI application output.

    The database is served by a small CGI program called BASERUNNER.EXE, which is accessed through the URL:


    (This is the URL which provides the WML-formatted output).

    I'm already using the same database to run the regular HTML site, with a similar URL:


    As you can see, the extension is the same. Therefore, the WAP version is not recognized by WAP devices because of the wrong header.

    How do I tell the server how to send the correct MIME header so that WAP browsers recognize the output? And is it possible to make these 2 configurations (WML
    output and HTML output) coexist on the same server?

    The site is hosted on a shared "virtual" server (IIS 4.0). I'm not the admin, but I could ask them to set the MIME types it I could find the correct parameters.

    Thanks in advance!

    You should be able to make the CGI program be the thing to output the MIME type. In my experience the first line of most C/perl CGI programs is something like:

    print "Content-type: text/htmlnn";

    You need to change this to:

    print "Content-type: text/vnd.wap.wmlnn";

    Hope this helps,
