<div class="gmail_quote">Sorry, I am not sure I understood you correctly. It is used in headers_in for look up into headers_in_hash OK. But what about headers_out?</div><div class="gmail_quote"><br></div><div class="gmail_quote">
ngx_http_proxy_process_header parses the upstream response headers using ngx_http_parse_header_line, thereby setting hash/lowcase_key. This function sets headers_out which I use. The question I have is, is it safe to use the headers_out.....lowcase_key, should I check for headers_out.headers.part.elt[it].hash before I can use lowcase_key or should I check for something else?</div>
