Tobie,
Thanks for your help. My Web server (Apache/2.0.58 running on IBM AS/
400) is passing the appropriate header information (i.e. 'Content-
Type: application/json'), but when the response is delivered, it's
garbled (i.e. it contains non-printable characters, etc). It's like
it's being sent is some strange or unknown character set. While still
garbled, I notice changes in the response when I specify various
charsets in the Content-Type header (e.g. 'application/json;
charset=ISO-8859-1'), however the response remains garbled in all
cases. Again, here's an example of the response:
�% ���������� [EMAIL PROTECTED] ������ z k% ������� z k% ������ z k
% ���� z@ % �%
Does setting the evalJSON property to 'force' introduce a heightened
security risk with regard the the execution of malicious JavaScript
code? I got this impression from the Prototype documentation, but it
may be an incorrect impression. Thoughts?
