ASP.NET - Handle redirect after async post back
I have an ASP.NET web application that uses Upda开发者_开发百科te Panels. The web application is integrated in a SiteMinder SSO environment.
The problem occurs when Siteminder thinks it is time to re-authenticate the user. When the user performs an action that results in an async postback, Siteminder catches this request and sends back a redirect response to its login page.
My ASP.NET page does not expect this and throws an PageRequestManagerParserErrorException.
My guess is that I have to catch this redirect response in client code (using a PageRequestManager event?) and handle the redirect correctly.
But how?
I have the same problem. I found one solution here: http://forums.asp.net/t/1470176.aspx/1
I ended up with the following javascript on each page:
function pageLoad() {
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
}
function EndRequestHandler(sender, args) {
if (args.get_error() != undefined) {
if (args.get_response().get_responseData().indexOf("<HTML><HEAD><TITLE>") == 0) {
args.set_errorHandled(true);
__doPostBack("", "");
}
else {
// not my error so let the default behavior happen
}
}
}
It stops the page from beaking completely but it does do a full page refresh instead of an async postback once SSO has timed out on the client.
