非www的redirect规则到www.sitedomain.com工作，但CDN域请求的豁免规则被忽略（ add input =“{HTTP_HOST}”pattern =“cdnprefix.azureedge.net”negate =“true” ）和CDN请求redirect到www.sitedomain.com。
规范redirect部分是否可以修改为忽略CDN域？
<rule name="Redirect non-www to www.sitedomain.com" stopProcessing="true"> <match url="(.*)" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false"> <!-- domain is not canonical --> <add input="{HTTP_HOST}" matchType="Pattern" ignoreCase="true" pattern="^sitedomain\.com$" /> <add input="{HTTP_HOST}" pattern="^www\.sitedomain\.com$" negate="true" /> <add input="{HTTP_HOST}" pattern="cdnprefix\.azureedge\.net" negate="true" /> </conditions> <action type="Redirect" url="https://www.sitedomain.com/{R:1}" redirectType="Permanent" /> </rule> 再加上有效的HTTP – > httpS topredirect规则（分解为简化CDN免除规则的解决scheme），看起来像这样：
<rule name="Redirect to https"> <match url="(.*)" /> <conditions> <add input="{HTTPS}" pattern="Off" ignoreCase="true" /> <add input="{REQUEST_METHOD}" pattern="^get$|^head$" /> </conditions> <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Permanent" /> </rule> <rule name="Redirect non-www to www.sitedomain.com" stopProcessing="true"> <match url="(.*)" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false"> <!-- domain is not canonical --> <add input="{HTTP_HOST}" matchType="Pattern" ignoreCase="true" pattern="^sitedomain\.com$" /> <add input="{HTTP_HOST}" pattern="^www\.sitedomain\.com$" negate="true" /> <add input="{HTTP_HOST}" pattern="cdnprefix\.azureedge\.net" negate="true" /> </conditions> <action type="Redirect" url="https://www.sitedomain.com/{R:1}" redirectType="Permanent" /> </rule>
