Re: Content-type issue with application/json and application/javascript

I am pretty sure we always ensure the data is in UTF-8 when sending content that has a content type that is anything but "text/...."

Subject: Re: [WEB400] Content-type issue with application/json and application/javascript

Hello Henrick. That's sort of what I suspected. Do I have to change the
CGI program to produce ASCII output, or is there a way to tell Apache to do an EBCDIC to ASCII conversion on an "application/javascript" content type?

We have several CGI programs that generate javascript, usually JSON.
For years we have set the content type to text/plain or
text/javascript. I'd like to start using the more standard
"application/json", but I am

hitting

a major snag. The output is garbage. I get the exact same output
when I set the content-type to application/javascript.

Just to verify this was related to CGI output, I used AddType to
change

the

content-type of static JavaScript files to "application/javascript".

Those

files look fine, so this must have something to do with it being CGI
output.

I don't really know what is up with the output, but I know it isn't
EBCDIC. It doesn't convert. Garbage in, garbage out. Changing the

content

type back to text/javascript sets everything right.

Anyone have any guesses what is going on here? We use CGIDEV2 under
IBM i 7.1. The default CCSID of our CGI jobs is 37.

Just so we are clear on one thing. We had the following settings in
our HTTP Conf:

DefaultFsCCSID 037
CGIConvMode %%EBCDIC/EBCDIC%%

I commented both settings out and it had no impact on the output
whatsoever. All of our CGI programs that use content type of "text/*"
seemed to work. The ones using "application/javascript" or
"application/json" for content type still looked like garbage. The
only guess I have is that mod_cgi sees that the content-type starts
with "application" and treats the output as binary, but I have no
idea how I

can

tell mod_cgi to treat "application/javascript" as text, or if that
is

even

the issue.

I am hoping someone has an idea. I know Apache pretty well, but
this one has me stumped.
