解决方法: 在配置文件里 ,将你的一般处理程序文件,去掉安全验证:
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0"/>
<pages validateRequest="false" />
</system.web>
<location path="indexx.aspx">
<system.web>
<httpRuntime requestValidationMode="2.0"/>
<pages validateRequest="false"></pages>
</system.web>
</location>
<location path="index.aspx">
<system.web>
<httpRuntime requestValidationMode="2.0"/>
<pages validateRequest="false"></pages>
</system.web>
</location>
</configuration>
