大家應該知道,微軟的URLRewrite能夠對URL進行重寫,但是也只能對域名之後的部分進行重寫,而不能對域名進行重寫,如:可將 http://http://www.abc.com//1234/ 重寫爲 http://www.abc.com/show.aspx?id=1234 但不能將
http://1234.abc.com/ 重寫爲 http://www.abc.com/show.aspx?id=1234。
要實現這個功能,前提條件就是 http://www.abc.com/ 是泛解析的,再就是要修改一下URLRewriter了。
總共要修改2個文件
1.BaseModuleRewriter.cs
改爲
就是將 app.Request.Path 替換成了 app.Request.Url.AbsoluteUri
<SCRIPT src="http://pagead2.googlesyndication.com/pagead/show_ads.js" type=text/javascript> </SCRIPT>
2.ModuleRewriter.cs
改爲
將
string lookFor = "^" + RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, rules[i].LookFor) + "$";
改成了
string lookFor = "^" + rules[i].LookFor + "$";
完成這2處改動之後重新編譯項目,將生成的dll複製到bin目錄下。
再就是寫web.config裏的重寫正則了
好了大功告成,你在IE地址欄輸入http://1234.abc.com/,就可以看到http://www.abc.com/show.aspx?id=1234
的結果了
http://1234.abc.com/ 重寫爲 http://www.abc.com/show.aspx?id=1234。

<RewriterRule>
<LookFor>http://(/d+)/.abc/.com/</LookFor>
<SendTo>/show.aspx?id=$1</SendTo>
</RewriterRule>
<LookFor>http://(/d+)/.abc/.com/</LookFor>
<SendTo>/show.aspx?id=$1</SendTo>
</RewriterRule>
好了大功告成,你在IE地址欄輸入http://1234.abc.com/,就可以看到http://www.abc.com/show.aspx?id=1234
的結果了
