nginx: src/http/modules/ngx_http_range_filter

annotate src/http/modules/ngx_http_range_filter_module.c @ 8057:ae2d62bb12c0

Range filter: clearing of pre-existing Content-Range headers. Some servers might emit Content-Range header on 200 responses, and this does not seem to contradict RFC 9110: as per RFC 9110, the Content-Range header has no meaning for status codes other than 206 and 416. Previously this resulted in duplicate Content-Range headers in nginx responses handled by the range filter. Fix is to clear pre-existing headers.
