Here's what happened:
The a.aspx page executes an URL string to access b.aspx and then the b page returns a value to a
a. aspx. cs 1 block of code
string result = "";
string url = "http://localhost:1759/textWeb/b.aspx";
result =exec_url(url);
Label1.Text = result;
public string exec_url(string url)
{
string result = "1";
WebRequest request = WebRequest.Create(url);
try
{
request.Timeout = 20000;//20 Second timeout
WebResponse response = request.GetResponse();
Stream resStream = response.GetResponseStream();
StreamReader sr = new StreamReader(resStream);
result = sr.ReadToEnd();
sr.Close();
resStream.Close();
}
catch
{
return "1";
}
return result;
}
b. aspx page code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title> No title page </title>
</head>
<body>
<form id="form1" runat="server">
<div>
</div>
</form>
</body>
</html>
b. aspx. cs code:
public partial class test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Response.Write(" hello Ha ha! ");
}
}
Runtime: Label content appears normally at the first session but will prompt when you click the button without refreshing the page
System. Web. HttpException: The status information on this page is invalid and may be corrupted
Causes:
It turns out that the first time label loaded the content, the load was ES40en.aspx
< form >
Hello, haha!
< /form >
Click again and the principle should look like this:
< form >
Hello, haha!
< form >
Hello, haha!
< /form >
< /form >
So there was a mistake!
The solution: Remove the form tag from ES84en.aspx
