I run OpenSEF 2.0.0-RC5_SP2
and I've been on the j-prosolution Forum to understand what is a "404 header"...
as long as I understand, my release of OpenSEF does not manage it ? not good....
I did only what was suggested in OpenSEF configuration :
- my 404 page points to a static content article ( I its relative url in the 404 configuration of OpenSEF)
- when I get it in the browsers, I see nothing specific in its header ?
so if I understand well (it starts to be a bit complex for me...) I need to make match the text which is inside the static "404" page with the "404 cache config" for the things to work ?
however, I remain with a wrong 404 page (wrong meaning that it is not with the header it should have)

wahoooo.... (i'm lost in space)
