Hi,
I have some questions regarding application pools and the different types of web sites in asp.net.
As far as I understand, an application pool will reset after 20 min idle time by default.
But once that occur, we are experiencing a huge perf hit when accessing the first page in the site.
I get the impression that the site will start recompiling again.
The project type is the vs.net 2005 "web Site" project that does not compile the codebehind into a static dll in the bin folder
I can't recall ever having this problem when I have worked with the older "web Project" projects.
So is the problems I'm experiencing related to the fact that the codebehind is not precompiled and that the reset of the app pool throws away the compilation result of the previous worker processes?
or is the perf hit simply related to alot of overhead in starting up the worker processes?
Any ideas?
Will the problems go away if we change the project into a "web project" with precompiled codebehinds.
Or is the only solution to only allow the app pools to reset once every night or so?
|

A general answer to your post would be, Yes.
Precompiling the page will save you a lot of startup time.
I would untick the idle timeout, and instead recycle the processes at night when noone is using the homepage (if that's an option that is)
No recycling at all would be a bad advice though.
The default IIS setting seems to have the purpose to make it possible for even badly programmed pages with memoryleaks (AKA Crystal Reports) to work fairly well

Thanks,
Precompiling took care of the problems.
I do think that 20 min idle is way too drastic for the reset, but that is not up to me to decide here.
|
|
|
|
|
Just keep in mind that the app-pool idle timeout has to be the same or longer than the asp.net session timeout

Hi
We've encountered an authentication problem in a live-environment. Everything went fine in the test and stage environments. I'm out of ideas and need your help!
Setup:
- Impersonate is set to true in web.config
- Anonymous access is turned off
- Windows authentication is turned on
Authorization:
I have a setting in web.config, let's call it "AdministratorsGroup" and then I use this in the master page using Page.User.IsInRole to see if the current user is part of that active directory domain group.
This works perfectly fine in our test environments, but once installed in a live environment, an exception is thrown:
"Error in the relation between the confidence/reliance of the main domain and the domain which it relies on. "
Any idea's on what might have happened?

Hie all,
I have got a small problem, im using the code below to close a page. It works only when its under a button(ie button click event) but when i use a toolbar click event its not closing the page, even though it runs through the code without any errors. does anyone know whats wrong.
protected void RadToolBar1_ButtonClick1(object sender, Telerik.Web.UI.RadToolBarEventArgs e)
{
if ((e.Item.Text == "Save & Close")
{
string scriptString = "; window.close();
Page.ClientScript.RegisterClientScriptBlock(this.GetType()), "submitScript", scriptString);
}
}

That's a wrong implemenation that you are providing i think
omlac wrote: but when i use a toolbar click event
Register your script in PageLoad by using Button
RadToolBar1.Attributes.Add("onclick", "javascript:window.close();");
where RadToolBar1 is your button id on clicking of which the window should close ?
Sorry but which event are you talking about ?
Thanks and Regards

Thanks
im doing everything in the radtoolbar clickevent, i have got a lot of other items on toobar, say "save" button and "save & Close" , so only when i click Save & close is when i want to close the page.
does the line RadToolBar1.Attributes.Add("onclick", "javascript:window.close();"); allow me to close only when button on toolbar is "save & close"
|
|
|
|

Yes,I supposed that "save & close" text is of RadToolBar1 button ?
Are you showing any pop up window which are having all this button ?
My code will close the window whenever user click RadToolBar1 button
Could you explain what are you trying to do ?
Thanks and Regards

===================
//Add the above class in your 'App_Code' direcory of project. Add reference of "System.Threading,System.Windows.Forms,System.Drawing"
//Or Its better to Create a Class Library project for above Class "ImageFromHtml". And add the .dll as reference to your website.
//Place a One button on Form
//In Button_Click Event Write the below code
ImageFromHtml image = new ImageFromHtml();
image.Height = 800;
image.Width = 1020;
Bitmap img = image.ConvertPage(Request.Url.ToString());//This is url of your application which is running.
img.Save(@"D:\imge.jpg"); //Saving image in D directory

Hi,
How can i capture windows Download dialog box events??
Eg, I m opening file download dialog box. Then I want to know what user do on that, means which button he press, "Save", "Open", "Cancel" or "Close".
How i know which event fires??
Please help in this regard.
Thanks in advance
|
|
|
|
|
my understanding of this process is that it uses a dialog internal to the browser running in its own thread, so there is no way to hook into it using javascript - or anything else served up from the web site.
please let me know if you discover differently!
