diff src/http/ngx_http.c @ 230:38e7b94d63ac NGINX_0_4_0
nginx 0.4.0
*) Change in internal API: the HTTP modules initialization was moved
from the init module phase to the HTTP postconfiguration phase.
*) Change: now the request body is not read beforehand for the
ngx_http_perl_module: it's required to start the reading using the
$r->has_request_body method.
*) Feature: the ngx_http_perl_module supports the DECLINED return code.
*) Feature: the ngx_http_dav_module supports the incoming "Date" header
line for the PUT method.
*) Feature: the "ssi" directive is available inside the "if" block.
*) Bugfix: a segmentation fault occurred if there was an "index"
directive with variables and the first index name was without
variables; bug appeared in 0.1.29.
