nginx: src/http/ngx_http_file

annotate src/http/ngx_http_file_cache.c @ 633:f971949ffb58 release-0.3.38

nginx-0.3.38-RELEASE import *) Feature: the ngx_http_dav_module. *) Change: the ngx_http_perl_module optimizations. Thanks to Sergey Skvortsov. *) Feature: the ngx_http_perl_module supports the $r->request_body_file method. *) Feature: the "client_body_in_file_only" directive. *) Workaround: now on disk overflow nginx tries to write access logs once a second only. Thanks to Anton Yuzhaninov and Maxim Dounin. *) Bugfix: now the "limit_rate" directive more precisely limits rate if rate is more than 100 Kbyte/s. Thanks to ForJest. *) Bugfix: now the IMAP/POP3 proxy escapes the "\r" and "\n" symbols in login and password to pass authorization server. Thanks to Maxim Dounin.
