Legacy Konqueror compatibility in AJaX

[Fredrik Johansson]

Hi !

Il share my experience of XHR in khtml, which starts at around 3.4
I think XHR was first included in 3.3, I may be wrong though.

When you get a response from XHR and you use cache and content isnt changed, 
the server responds with a 304 status code.
Moz and IE translates this to a 200 and from 3.4.2 or 3.4.3 khtml does that 
convertion on a async XHR, but not a sync one.
So make sure you add a 304 as a vaild response.

The UTF-8 encoding thing below appiles to a plain textfile with no charset 
info, such as a JS script.
If you are grabing js and eval that after retrieval and it contains non latin 
strings, you can hack around it by inserting a :

/* <?xml version="1.0" encoding="UTF-8" ?> */

in the top of your js file. Note the javascript comment, makes it evalable.

I wrote a patch for this and send it to this list some time ago, and was 
pointed to adawit for reviewal.
Sorry to say I havent got hold of him yet (mail bounce), and I have been to 
busy at work lately so the charset and sync load patch will probably not make 
it into 3.5.4

Regards
Fredrik Johansson
