I keep getting this exception intermittently, it looks like a search engine is hitting my page even though I have a robots.txt file. What is weird is look at the "Event" from Management Console (below). The
"Request URL" has "&" in the URL. If you copy and paste that request URL you get the same exception (my site hides the exception of course) If you copy and paste the URL and replace "&" with just "&" then there is no exception and it returns a javascript
file. When I visit the reports page myself, everything works properly. Like I said I am picking this up in my error logs and it throws quite a few exceptions all right in a row (like 5 of the same exceptions at the same time down to the second)
Has anyone encountered this? I am using this in my web.config:

I have not tested this yet but in
theory it should work....
Sub Application_BeginRequest(ByVal sender
As Object,
ByVal e As EventArgs)
' Fires at the beginning of each request
If Not Request.ServerVariables.Item("HTTP_X_BLUECOAT_VIA") =
Nothing Then
HttpContext.Current.RewritePath(Request.Path & "?" & Replace(Request.QueryString.ToString, Server.UrlEncode("amp;"),
"&"), True)
End If
End Sub
I know it has been some time since this post, but i am having the exact same problem as the original poster. Your solution looks promising but I'm curious how I determine what the proxy is. I've looked in my server variables and don't seem to have one--though
I don't believe it's specifically Bluecoat.
Ryan, Curious where you put your code? In the page with the control in it? And how will I know if it is that variable exactly as you mention or where can I find that blue coat variable?
C# version of ryanloken's answer (tested in Fiddler):
protected void Application_BeginRequest(Object sender, EventArgs e)
{
// Fires at the beginning of each request
if (!String.IsNullOrEmpty(Request.ServerVariables["HTTP_X_BLUECOAT_VIA"]))
{
string original = Request.QueryString.ToString();
HttpContext.Current.RewritePath(Request.Path + "?" + original.Replace(Server.UrlEncode("amp;"), "&"));
}

It may be help, try this:
Install Report Viewer
C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\BootStrapper\Packages\ReportViewer\ReportViewer.exe
Second step:
Give full access to 'NETWORK SERVICE' to c:\windows\temp directory.
Good Luck,

I am getting this error too. I noticed that error occures only for users who are using Bluecoat proxy. They have HTTP_X_BLUECOAT_VIA header.
This proxy URL encodes ampercent in a query string, which breaks ReportViewer.
QUERY_STRING=OpType=Resource&Version=8.0.50727.762&Name=Icons.PrevPage.gif
It seems to be a proxy's issue.

Hello,
Has anybody been able to see if Ryan Loken's workaround resolves the problem?
I could test it however my site only generates this error infrequently - so it could be a month or more before I know if it has had any effect.
Thanks,
Mike

This worked for me. I have not seen the error again in our production environment.
