I've been playing with this for a few days. How do I get an aspx page to cache on the client so that the server returns a 304 response code? I've tried this:
[Code]....
But it doesn't seem to work. Or maybe, how do I -- from inside my code -- return the 302 directly to the browser?
How do you cache an aspx page call on the client?
The aspx page returns an asset and looks like this:

We have tried with Output Cache, with caching in the code behind, but the only result we get is server side caching (by IIS7).
In the header of the response cache-control is set to public and expiration time is set (to 14800 as set in output cache profile).
I have a ASP.Net web application that generates files. These files need to be stored on the client machine.
The web application should ask the user for a directory on the client machine where the files are to be stored. How do I achieve this?
I have two applications one already installed at client side, and a web application hosted on some server, in web application there is a page from which there is an option to run that application,how can I do this.
View 3 RepliesWe have a wfc layer that wraps the business classes and database access and use a client that lives on the database layer. Amongst our group we are attempting to form standards. Some want to have the client call the web method and pass the page they are requesting and the page size. Pass that to the database and then page in SQL Server use RowNum.Some want to cache the full list of objects in http cache on the service tier and page in memory. They concern here is memory use on the server.
Which would be best for a medium number of users with potentially large number of records to manage (say 30K) Is it better to cache them all in memory and work from there or page at the database as the application scales?
I need to enable caching in my asp.net application, but I do not want to use the webserver's memory for holding cache objects. If I add the page directive for output caching will the page be stored in the asp.net cache object?
View 2 RepliesMy web client requires client-side output caching since it makes use of its own Back and Forward buttons (which basically just call the browser back/forward buttons).
The issue I'm having, however, is (of course) when the user signs out of the app. The client-side output cache remains so anyone can click the "back" button and it appears to be signed in again. I've researched a few solutions, but most involve server-side output caching or no output caching at all.
I've had success with server caching and HttpResponse.RemoveOutputCacheItem, but unfortunately I need the client side caching.
Is it at all possible to clear this client side output cache upon logging out?
Usual javascript files can be cached on a client-side if web server sets the expiration. If user has once downloaded it, it will be cached by his browser.And what about AjaxControlToolkit ToolkitScriptManager? Are combined JS files cached on a client? How can expiration time be managed?
View 1 RepliesI have a server/client architecture where the client hits the ASP.NET server's service at a certain host name, IP address, and port. Without thinking, I logged on to the server and set up permanent HTTP301 redirection through IIS from that service to another URL that the machine handles via IIS (same IP and port), mistakenly thinking it was another site that is hosted there. When the client hit the server at the old host name, it cached the permanent redirect. Now, even though I have removed the redirection, the client no longer uses the old address. How can I clear the client's cache so that it no longer stores the redirect?
I have read about how permanent HTTP301 can be, but in this case, it should be possible to reset a single client's knowledge of the incorrectly-learned host name.

Is it possible to cache the response of a http handler on the server and on the client?This doesn't seem to be doing the trick:
_context.Response.Cache.SetCacheability(HttpCacheability.Public);
_context.Response.Cache.SetExpires(DateTime.Now.AddDays(7));
NET Cache stores values on the memory of the client or on the server?If it stores on the memory of the client then can i store the values in Cache instead of cookies - as this will improve speed of my application
View 4 RepliesAssume a simple aspx data entry page in which admin user can upload an image as well as some other data. They are stored in database and the next time admin visits that page to edit record, image data fetched and a preview generated and saved to disk (using GDI+) and the preview is shown in an image control.
This procedure works fine for the first time however if the image changes (a new one uploaded) the next time the page is surfed it shows previously uploaded image. I debugged the application and everything works correct. The new image data is in database and new preview is stored in Temp location however the page shows previous one. If I refresh the page it shows the new image preview. I should mention that preview is always saved to disk with one name (id of each record as the name).
I think that is because of IE and other browsers use client cache instead of loading images each time a page is surfed. I wonder if there is a way to force the client browser to refresh itself so the newly uploaded image is shown without user intervention.
I have to implement the print functionality on aspx page like on click of print image icon user will be able to get the print out of aspx page .aspx page will contain the server controls like textboxes , Gridview etc which one approach will be the best server side or client side printing ?
View 4 RepliesI have a masterpage that calls all kind of external files from the server on startup, mainly css and jquery files. So, problem is, every time I open the page, there are a lot of roundtrips to the server to request these files.After the initial loading has been done, everything is ok.
Will it be possible to cache these small files to the client side, with a predetermined expiration date, so when i next open the page, I will keep the roundtrips to the servers at a minimum?
what i wanna do is:
there is an dropDownList in the master page with 4~5 items.
i've prepared 4~5 sub-page related to the above item. when the dropDownList.ItemChanged, the subpage content will show their own page.
use html iframe to include another aspx page.
in my cs code:
[Code]....
but when i change the item in the dropdownlist, the error pops up:

My requirement is to get the file size in client side. there is no problem in FF but in IE you can't do that unless u r using an activeX object. So we thought of putting it in browser cache and reading the file size from there and when we post it to the server we will be taking it from the cache and send it to the server.

View 1 RepliesHas anyone been able to cache .aspx pages using the HTML cache manifest? I am porting an html application over to asp.net (and mvc2) and I get a 404 error when trying to cache any *.aspx page. Other files still cache normally (.js, .css, etc). I have changed permissions, handlers, and file names and still no luck. Below is the actual manifest:

When I update a js file in my asp.net project, I refresh the browser and the change shows up as expected. If I change a css file or an .aspx file, the change does not show in the browser. Not when I clear the browser's cache, not when I restart IIS (iisrestart). What could this possibly be?
PS. I have tried chrome and firefox
I have a web form where most of the aspx markup never changes. Only a few controls change from time to time. As I have read through some articles it seems I have to create a custom control to enable partial page caching. Is there another way where I can cache all but a few controls?
