A bit of history on this. The content-type in this bit of code was determined more than three years ago by testing with several old major web browsers. At the time, 'application/x-javascript' was the content-type that reliably told the web browser to use its javascript parser on the document so that the rpc data could be used. Other settings did not work on all of the web browsers I tested. So, this content-type was decided empirically (a long time ago), not from specification. It maybe should continue to be the default for compatibility with creaky old web browsers. But maybe it can be changeable (if you *really* know what you are doing) so that the outgoing document can meet the expectations of client libraries. - Jim Washington _______________________________________________ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
