Re: YAJL

Then I assume your program should set the Content-Length http header if it is the one generating the response.  Then chunked can be avoided.

Chunked is an option that is used for performance reasons.  Without chunked, the server would need to wait for all the data to determine payload length.

It is an Angular program that is currently using Firebase to store its data.
The call to Firebase does not return chunk data, it returns just the JSON
data.

I am writing an RPGLE/YAJL back end server executed through Apache to
replace the firebase call.  The plan was to only swap the URL address.  I
don't really want to have to modify all of the Angular calls to strip the
extra characters and I have not found a way in Angular to say this is chunk
data so automatically strip it.

I don't mean to be a jerk with this.  I just don't understand why it DOES
work one way with Firebase but it DOESN'T work that same way with
Apache/RPGLE/YAJL.  Is Firebase the one that is wrong and doing something
non-standard?

Please tell us what you are using to make the request and get the data back.
Did you write some socket application yourself or are you using another
solution?

Whatever that application is, that's the issue.  It's not processing the
returned chunked data properly.
