We are writing a portal and like every portal we store html data in Db fro Modules. So I thought that I can cache each module in files. I use OnLoad event to check if there is a cache file for this Module, use that and else create cache file:
if (!IsPostBack)
{
string Path = AppDomain.CurrentDomain.BaseDirectory + "CacheModules" + ModuleId + ".dat";
if (File.Exists(Path))
{
Controls.Clear();........
where external files / images are being loaded from. By this I mean that I'm aware that external JS files / Images are cached on the first load of a page. What I'd like to have is a tool that confirms to me that on subsequent requests these files are in fact being loaded from the users cache rather than downloading the file again.
View 3 RepliesI configured cache dependency on a file on the server, the cache dependency event stops responding to file changes once in 2 or 3 days. After I perform IISReset on the server, it works fine.

View 1 RepliesIn an ASP.NET web app written in VB.NET, I need to load and store a large read-only hash table that is frequently accessed by the application. It only needs to be loaded once on application start, is never updated and can be accessed by any session at any time.
If I load the hash table into a private member in a (global) module, a lookup to it takes one 20th of the time compared to storing the hash table in the Application or Cache object. Is there any reason why I should not do this, or should Application or Cache always be used to store in-memory objects in an ASP.NET web application?

We have a function that changes the iframe height at the window.onload event so we can adjust it to the page contents. The problem is that after clicking in an asp:menu the height its restored to its default and the window.onload event doesnt fire...so we need the event that would fire in subsequent loads (tried window.unload but didnt trigger)
The resize function cant be called on the asp:menu click because the window wouldnt have finished loading so the height calculation would fail...
I have the following download request in javascript:
var exportWindow = window.open('Download.ashx?source=1', '');
exportWindow.onload = function() {
alert('finished');
};
My problem is that the above alert box does not appear. The download.ashx sets up the following response (which will be saved as a csv file), which works fine.
context.Response.ClearContent();
context.Response.ContentType = "application/text";
context.Response.AddHeader("content-disposition", "attachment; filename="" + fileName + """);
context.Response.Write(resultWriter.ToString());
context.Response.Flush();
context.Response.Close();
If I replace the download.ashx with a normal aspx page, then the alert appears. So my question would be: is it possible to know programatically when the dowload.ashx returned with a response?(using FF3)
I put following on Page_onload event, I am not sure why it is not working. However when I use with dropdown, it is working fine.

View 5 RepliesI am writing an asp.net HTTP module which needs to read configuration data once from a local file (say config.xml stored in application root directory) and then based on configuration perform some processing on incoming requests.
Since there is no Application_Start/Application_init hooking available in Asp.NET modules, what would be the best way to handle the scenario. I am trying to avoid reading configuration file each time a request comes. Ideally, I want to read the config file when application starts.
I need to code this in http module only and do not want to use Global.asax

View 3 RepliesI have a module that subscribes to PreRequestHandlerExecute event, which uses the Session object. When i set the webconfig compilationdebug flag to false, the Session object is null when making requests to the web service. It works fine for .aspx requests, but only have problems for .asmx. When i set the debug flag to true everything works fine. I need to set this flag to false for production, but can't seem to get it work.I'm using II7 and the integrated pipeline, so this event will fire for all requests.

HOW TO RUN THE JAVASCRIPT FUNCTION ON PAGE ONLOAD EVENT IN CONTENT PAGE OF MASTER PAGE.?
means i have masterpage and the content page of master page namely default.aspx in vb.net
My problem was that .
i wanna run javascript function in Default.aspx and i have called the function
body onload in master page..
when i run my website it shows the error
"" Microsoft JScript Runtime Error : Object Expected ""
i have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.
all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.
but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.
I would like ask you for some ideas how can I write mechanism that will be automatically read files from folder. I don't know how to schedule the write task. I want to check for new file everyday and if the new file is in the folder read it.
View 2 RepliesI read few xml files from a location and cache them using Http context cache. Anytime the xml files changes i have to do a IISReset to view the latest changes.
I use this
System.Web.HttpContext.Current.Cache
I have to use the caching as i don't want to read all the xml files all the time. i read it once and caches them for a day. They get reset whenever apppool recyles or anyone manualy do a IISReset.
Is there anyway in asp.net to invalidate the cache if someones changes the xml file.
I have asp.net application. I'm using external javascript files in my application. When I test my site with page speed tool from google it says that following resources are missing a cache expiration. also some of the images and css files.
