请教:修改了httpd.conf,为何访问cgi仍会有405错误?

bulin

偶已修改了httpd.conf中的代码:
[code:1]
ScriptAlias /cgi-bin/ "/usr/local/apache/htdocs/cgi-bin/"
<Directory "/usr/local/apache/htdocs/cgi-bin/">
AllowOverride None
Options ExecCGI
</Directory>
[/code:1]
不知为何访问cgi文件时仍提示:
Method Not Allowed
The requested method POST is not allowed for the URL /cgi-bin/blast.cgi.
是否还有哪些地方要求设置?请帮忙~~~~~
