Hi all,
Why does Apache httpd strip of the custom response headers when the
resp-code is "304-Not Modified"?
I have the following scenario :
A client sends request to Apache httpd, and the request is handled by some
module. The module's content handler sets the response status to
HTTP_NOT_MODIFIED, and adds some custom response headers to "headers_out".
But, ap_http_header_filter() strips all the headers other than some specific
headers. Why should it not send the custom headers?
What happens if those headers are add to err_headers_out instead?
Those put in err_headers_out are treated differently in certain cases.
Quoting from httpd.h:
* The difference between headers_out and err_headers_out is that the
* latter are printed even on error, and persist across internal redirects
* (so the headers printed for ErrorDocument handlers will have them).
