apache - Cloudflare bug random 302 redirections -

i've issue cloudflare, (randomly) have 302 redirections on random non-existing subfolders, give examples : get /en/home > 302 > /en/home/swetz > 302 > /en/home > 302 > /en/home/qutis > 302 > /en/home > 200 /en/home > 302 > /en/home/zaiue > 302 > /en/home/zaiue/widut > 302 > /en/home > 200 when disable cloudflare, seems work , no sign of strange redirections. i've noticed these redirections happen on resources when header "cf-cache-status" set miss. it's annoying because "err_too_many_redirections" happen totally breaks website : javascript, styles , images not loaded... please open support ticket & can take look. wouldn't add redirect unless set pagerule instructing so, sounds may have configured incorrectly. forwarding & cache status different things & shouldn't have play here.
