I'm currently looking at this Wikipedia article: List of HTTP status codes and it has the following sections that represent HTTP status code classes: 1xx, 2xx, 3xx, 4xx, 5xx.
The same can be found in the Apache documentation (Custom Error Responses):
Although the Apache HTTP Server provides generic error responses in the event of 4xx or 5xx HTTP status codes
As far as I know:
- four hundred - 400
- four-hundredth - 400th
- four-hundredths - 4/100
So the choice to pronounce might be one of the following:
- four hundredth
- four hundreds
I could not find any dictionary that has an entry for such a "term". I think that some video courses refer to them as "four-x-x" and "four hundredth". I don't remember where I've heard that, but even if I would that won't be credible enough to post here anyway.
Specifically, how to pronounce 1xx and 4xx? I'm asking both of them in case they might differ, because of singular / plural forms.
