Asp.net随记 Part 6(122-)

当在frameset结构下引入另一个站点的页面，就会导致cookie丢失，也就同样导致服务端的session会话的丢失(firefox 无此问题)，从而使得每次请求都要到SSO服务器去验证大大降低运行效率。查询 MSDN 得知加入Response Header：response.addHeader("P3P","CP=CAO PSA OUR")，就可以解决该问题。

141.C# 双引号替换单引号

root.ToString ().Replace ( "\"" , "'" ).Replace ( "“" , "'" );

140.ashx "XML解析错误：未找到元素"

139.Linq To DataSet 报错：“specified cast is not valid”

报错信息：

125.有关于cookie expire time的获取

比如：

我设置一个cookie过期时间
然后我把浏览器closed，再打开，再去debug
发现cookie的过期时间总是0001-01-01
原因：

Changing a Cookie's Expiration Date
The browser is responsible for managing cookies, and the cookie's expiration time and date help the browser manage its store of cookies. Therefore, although you can read the name and value of a cookie, you cannot read the cookie's expiration date and time.
When the browser sends cookie information to the server, the browser does not include the expiration information. (The cookie's Expires property always returns a date-time value of zero.)
http://msdn.microsoft.com/en-us/library/ms178194.aspx

124.requestPathInvalidCharacters

如果你想不让ASP.net 替你拦截这些特殊字符，你需要设置如下Web.config的节：

<?xml version="1.0"?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<system.web>
<httpRuntime requestPathInvalidCharacters="" />
</system.web>
</configuration>

注意其中的requestPathInvalidCharacters 它是一个以逗号分隔的无效字符列表。不设置它时，它默认的无效字符集(以,分割)是后面7个：<,>,*,%,&,:,\

即，不设置这个属性，默认就是如下设置：

<?xml version="1.0"?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<system.web>
<httpRuntime requestPathInvalidCharacters="&lt;,&gt;,*,%,:,&amp;,\" />
</system.web>
</configuration>

如果你想这些字符全部不受限制，就应该设置 requestPathInvalidCharacters="" , 如果是部分字符受限制，部分字符不受限制，就需要在 requestPathInvalidCharacters 中设置需要受限制的字符，不受限制的不用设置。

123.The request was aborted: The request was canceled.

Global.asax

void Application_Start (object sender , EventArgs e) {

//设置服务idleTime

System.Net.ServicePointManager.MaxServicePointIdleTime = 4000;

}
