IHS 403解决办法

在ihs的配置文件中的<IfModule mod_proxy.c>模块中加入下面的语句即可
AllowCONNECT 443 563 5000

=========================IBM官方的解释
AllowCONNECT

Compatibility - AllowCONNECT is only available in Apache 1.3.2 and above.
Context - Server configuration, virtual host
Default - AllowCONNECT 443 563
Module - mod_proxy
Status - Base
Syntax - AllowCONNECT <port list>
The AllowCONNECT directive specifies a list of port numbers to which the proxy CONNECT method may connect. Browsers use this method when an HTTPS connection is requested and proxy tunneling over HTTP is in effect.
By default, only the default https port (443) and the default snews port (563) are enabled. Use the AllowCONNECT directive to override this default and allow connections only to the listed ports.
