nginx-0.3.50-RELEASE import
*) Change: the "proxy_redirect_errors" and "fastcgi_redirect_errors"
directives was renamed to the "proxy_intercept_errors" and
"fastcgi_intercept_errors" directives.
*) Feature: the ngx_http_charset_module supports the recoding from the
single byte encodings to the UTF-8 encoding and back.
*) Feature: the "X-Accel-Charset" response header line is supported in
proxy and FastCGI mode.
*) Bugfix: the "\" escape symbol in the "\"" and "\'" pairs in the SSI
command was removed only if the command also has the "$" symbol.
*) Bugfix: the "<!--" string might be added on some conditions in the
SSI after inclusion.
*) Bugfix: if the "Content-Length: 0" header line was in response, then
in nonbuffered proxying mode the client connection was not closed.
