Question

我有一个ASP.net表单页面作为代理。

我的网站正在从其他网站companyX.com下载一些内容。

companyX.com的网站正在使用sharePoint。

我的网站正在从companyX.com下载HTML并成功将其添加到我的页面，但是，在Page_Init, Page_Load和Page_Unload之后但在Render之前我的网页正在抛出下面粘贴的错误

我的网站没有安装任何sharepoint。但是，看起来asp.net中有一些东西正在处理我页面中的HTML内容，识别一些sharepoint标签然后尝试加载sharepoint。我很想关掉这个！

我的网页确实有EnableViewState="false" EnableViewStateMac="false" ValidateRequest="false"

错误：

Answer 1

ASP.net并不想加载Sharepoint，它试图弄清楚你正在检索的页面中包含的ViewState，但却不能，因为它是由另一台具有不同机器密钥的服务器构建的。

我个人会在渲染阶段之前从检索到的HTML中删除ViewState隐藏字段，否则您可能会遇到可能会随机混淆问题的持续问题。

我终于通过在页面中添加以下内容来修复它：

Protected Overrides Function LoadPageStateFromPersistenceMedium() As Object
    Return Nothing
End Function

如何阻止asp.net尝试加载sharepoint？
