HTTP Status Codes in Internet Explorer

Question

I usually translated request.status == 0 as a connection failure.

However, I found that Internet Explorer sometimes uses HTTP 12007.

What would you recommend to the rules that I use when deciding whether to tell the user "Internet failure" by simply telling them "HTTP Status Code x"?

Is 12007 the only code for this kind of thing? (except zero)

Answer 1

status values ​​above 12000 come from Windows and tell you that the HTTP request itself failed (i.e. there was never a request).

You can find a list of these error messages here .
