i think u have to add Headers to restrict Back view
Try this
Response.CacheControl = "no-store";
Response.AddHeader("Pragma", "no-cache");
Response.AppendHeader("Cache-Control", "no-store");
|
|
|
|
|
if u r using master pages, code this in page load of master page or in page load of everypage
Response.Expires = 60;
DateTime now = DateTime.Now.AddMilliseconds(-1);
Response.ExpiresAbsolute = now;
Response.AddHeader("pragma", "no-cache");
int timeout = (Session.Timeout + 1) * 60;
Response.AddHeader("Refresh", timeout.ToString());
Response.AddHeader("cache-control", "private");
Response.CacheControl = "no-cache";
if (Session.IsNewSession)
{
Response.Redirect("~/Default.aspx");
}
and in logout
Session.Abandon();

This is fine but then when i am on a page (not logged out) and then i click back button it does not take me to the previuos page. ihave to click refresh to get the page.

browser cache always remains open..
you cant erase bowser cache programmatically.
Only you can do, is when user clicks anything on a page after logoff, throw some error messages.

Hi,
On the Page Load write
if Session("UserId")="" then
Response.Redirect("Login.aspx")
end if
if you click back now, the page will execute the page load na...it will go to login page.

You can use the AjaxControlToolkit
With it you can assign a calendar to a textbox with almost no code at all

Please Help Me Out :
I Want to Control The Client Browser i.e When ever a Specific URL Appears in the Client Browser Then The User Must be Redirected To Specified URL.

what is the problem with this.
If you programmatically want to do, just in your handler, try to transfer your response to the page if certain request occurs.
To get IP use
Request.Servervariables("REMOTE_ADDR")
You can get the absolute URI from this
Request.Url.AbsoluteUri
Now use Server.Transfer to the page.
Otherwise you can also use
<urlMappings enabled="true">
<add url="~/Info/Copyright.aspx" mappedUrl="~/Help/Copyright.aspx" />
<add url="~/Support/Contacts.aspx" mappedUrl="~/Help/Contacts.aspx" />
</urlMappings>
in Web.Config if you want this automatically.

This is frequent Issue with webserver, the same code works fine with local testing servers.
When the error is reported, it is fixed in few mintues by host.
Can anybody tell me, what is the exact issue behing this

something tells me it has to do with text Encodings.
Char '' is ASCII another value than in other ISO-languages.
In Word you can only store 2 bytes. That is why I use Writer.

Dear All,
Sorry for the repeat post, but i want the solution for this problem.
I have created a web application which includes crystal report for reports. Now the problem is that my reports were not working on the webserver.
The Application works Perfectly on my local machine in IIS and in .net environment but if i upload the same application on the web server it shows the error.
<per>
An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
What could be the solution
Thanks and Regards

Enable error reporting and see the error message. Once you fix it, disable the error reporting.

Make sure the versions specified in your config file exist in the server. This error may come when versions are not matching.
