Updatepanel 在代理下停止工作，并且仅发生在 IE 中
我们的网站上有一个更新面板，其中有许多链接按钮。
请注意，该网站在没有代理的
情况下在所有浏览器中都能正常工作，代理会将 url 从 www.mysite.net 更改为 0-www.mysite.net.edu.net 它在所有浏览器中也能正常工作，但 IE 的
问题是在代理下和 IE8 中，单击其中一个链接按钮时会出现错误，错误消息为

我不知道这里出了什么问题，似乎 IE 无法解析响应？
我打开 IE 开发人员开发工具，它显示了错误发生的位置，
Sys.Net.XMLHttpExecutor = function Sys$Net$XMLHttpExecutor() {
/// <summary locid="M:J#Sys.Net.XMLHttpExecutor.#ctor" />
if (arguments.length !== 0) throw Error.parameterCount();

var _this = this;

this._timedOut = false;
this._timer = null;
this._aborted = false;
this._started = false;
this._onReadyStateChange = (function () {
if (_this._xmlHttpRequest.readyState === 4 ) {
try {
if (typeof(_this._xmlHttpRequest.status) === "undefined") {
return;

catch(ex) {

_this._clearTimer();

请帮忙！感谢一百万！
We have an updatepanel in our site and there are a number of linkbuttons in it.
Please note that the site works fine across all browsers without proxy
the proxy changes the url from for instance www.mysite.net to 0-www.mysite.net.edu.net it also works fine in all browsers but IE
the issue is that under proxy and in IE8, it gives an error when clicking one of the linkbuttons, the error message is
"Webpage error details

I have no idea what goes wrong here, it seems that IE can't parse the response ?
I open IE developer developer tool and it shows where the error occurs
Sys.Net.XMLHttpExecutor = function Sys$Net$XMLHttpExecutor() {
/// <summary locid="M:J#Sys.Net.XMLHttpExecutor.#ctor" />
if (arguments.length !== 0) throw Error.parameterCount();
Sys.Net.XMLHttpExecutor.initializeBase(this);
var _this = this;
this._xmlHttpRequest = null;

this._responseAvailable = false;

this._timer = null;
this._aborted = false;
this._started = false;
this._onReadyStateChange = (function () {
if (_this._xmlHttpRequest.readyState === 4 ) {
try {
if (typeof(_this._xmlHttpRequest.status) === "undefined") {
return;
}
}
catch(ex) {
return;
}
_this._clearTimer();
_this._responseAvailable = true;
try {
_this._webRequest.completed(Sys.EventArgs.Empty);
}
finally {//<-----------------HERE IS WHERE THE ERROR OCCURS
if (_this._xmlHttpRequest != null) {
_this._xmlHttpRequest.onreadystatechange = Function.emptyMethod;
_this._xmlHttpRequest = null;

}
});

这是因为 UpdatePanel 期望其响应以特定方式格式化（“|”分隔）。如果任何内容篡改了传输中数据的格式，则它无法解析响应。
Sys.WebForms.PageRequestManagerParserErrorException - 它是什么以及如何避免它
Its because the UpdatePanel expects its Response formatted a specific way("|" delimited). If anything tampers with the format of the data in transit, it cannot parse the response.
