CSS In App_Theme Folder Gets Cached In Browser?
Dec 23, 2010The Stylesheet in the App_Theme folder gets cached in the browser. What should be the approach? so that whenever there is a new deployment the browser should take the latest stylesheets and not the one cached in the browser.
This was happening for other css(which are not in theme folder) too, so used custom control as mentioned in the link
[URL]
How this could be done for the CSS in the Theme folder?
Edit: The theme name is mentioned in the web.config as mentioned below. so its not just the html link tag which I had solved by using the method mentioned in the link.
<pages styleSheetTheme="Default">
<controls>
</controls>
</pages>

Configuration :: Client Browser Using Cached Files Instead Of Updated Version After Deployment
Oct 6, 2010We have an ASP.NET web application and it's hosted using IIS 6.0, in the app we have these several javascript and css files located in a folder, and for performance sake (according to YSlow) we set the folder content expiration header to 1 year. Everything worked just fine until recently when we deployed the latest build to the server, in which we had made some changes to those javascript and css files. For some reason after the deployment some of our end users don't see the latest changes when they connected to the app, even after they cleared the cache in IE. We have also restarted the IIS on the server and the problem still remained. When I went into the IE Temporary Internet Files folder on one of these machines I saw the files were still the older version and not the latest one, I had to manually delete the files from the Temporary Internet Files folder then they were able to see the latest changes. I'm baffled by this, how come only some users who couldn't see the changes but some others do (without having to do anything by the way), and how do I make sure that for future releases we won't have to do anything like what did (manually deleting the cached files)? For now I disabled the Content Expiration option in IIS for these files but I would like to know if there is a way that I can enable the content expiration (to help performance) but at the same time making sure when the files are updated, the latest version will be used for the end user (instead of the cached version)?

Web Forms :: Open A New Browser From Code Behind Without Causing Page Refresh
Feb 12, 2010I need to implement a "preview" functionality where people make changes to a form, click a button and a pop-up window displays the preview while the original form retains the user's changes in the various <textarea's. Right now, the preview is working, but when they come back to the form, their changes are gone, the page has refreshed. How do I prevent the page from refreshing? I need to go to the server to get the URL to the preview page.
View 6 RepliesBest Way To Initiate The Page Caching On The Server Side And Serve The Cached Page Upon?

Page Not Being Cached?
Nov 29, 2010 why all the resources in my page are being requested EVERY single time. E.g. my site.css returns the following headers (using fiddler):
HTTP/1.1 200 OK
Server: ASP.NET Development Server/9.0.0.0
Date: Mon, 29 Nov 2010 17:36:21 GMT
X-AspNet-Version: 2.0.50727
Content-Length: 9093
Cache-Control: public, max-age=2592000
Expires: Wed, 29 Dec 2010 17:36:21 GMT
Last-Modified: Mon, 08 Nov 2010 17:20:16 GMT
Content-Type: text/css
Connection: Close
But every time I hit refresh I see all the resources (css,js,images) getting re-requested. I have control over the headers returned for any and all of these resources, but I haven't figured it out yet.I have even debugged my ASP.NET app and the HttpModule is definitely being asked for the resources again.
EDIT:Ok, I removed must-revalidate, proxy-revalidate from the headers and that is getting me closer to where I want to be, now when I press back it still requests my css/js files when I press back.
Possible To Detect Whether An ASP.NET Page Is About To Be Cached
Apr 20, 2010Is it possible to detect whether an ASP.NET Page is about to be cached and if so, how?The HttpCachePolicy object provides only set-methods. The VaryByParams name-value collection is useless if values other than "None" and "*" are set as it impossible to enumerate them and you can only access them by key

.NET - Refreshing A Posted Page That Isn't Cached On IE
Mar 6, 2010Lets say you have a page with headers that tell the browser not to cache.Also, this page has already been posted back to itself.Now you hit the refresh button and you click cancel on the IE modal box with the "previously submitted..." message.You get "Webpage has expired". This doesn't happen in FF or Chrome.Is there a way to prevent the "Webpage has expired" message in IE?Since the page isn't cached, I guess IE has nothing to render.But if the page isn't cached and FF and Chrome shows it, I guess they just show the page as previously shown?
View 1 RepliesPrevent Page From Being Cached When Using OutputCacheAttribute?
Nov 9, 2010Is there a way to prevent a page from being cached based on some logic?
I want to cache anonymous access to a page, so I can set VaryByCustom="user" and have some magic in Global.asax's GetVaryByCustomString method. Ok. But I don't actually want to cache the page if the user's authenticated, only if it's not authenticated. Is there a way to specify this kind of thing?
The reason I want the data to not be added to the cache to begin with (instead of added with some random key) is that as the cache grows things get thrown out and I don't want the non-authenticated version to get thrown out.

How do I turn on those dropdowns for pages with code behind that uses <script> tags in the actual .aspx page?

Display Aspx And Aspx.cs Code Onto A Page Without The Browser?
May 29, 2010i have to give the user the option to upload his own aspx and aspx.cs files on to the server, adjust the hyperlink to point to a page which would do the following display the aspx and aspx.cs files code onto the page without actually rendering the code the browser should not understand anything, and while reading the files to display them the method be such that nothing is processed on the server regarding the code within the files to prevent from unnecessary problems many user would try to cause.
i have tried many ways of displaying it but it ends up on displaying the actual comments instead of the code. how to achieve the above. note main concentration is on asp.net and c# using vs08, so j script and ready-made tools be avoided if feasible
Page At One URL Using The Cached Page From Another URL?
Dec 1, 2010I'm pretty new to ASP.NET and very new to the concept of caching.
Using MCMS 2002, I built a template.aspx page that receives a "person_id" query string and builds pages accordingly. Several different departments at the school where I work are using this template to display faculty biographies. This much is all working correctly.
The Problem
The problems start happening when I try caching the page. When a person visits person_id=16175 on one department's page, then visits the same numeric bio on a different department page, it loads the cached page instead of rebuilding it. The problem, then, is that it has all of the wrong department branding. For example:
[URL]
It's the same person_id, but the URLs are obviously different. It would be great if the template would recognize the different URLs and ignore the cache. I'm assuming that the problem lies in the fact that both pages are being built using the same aspx page on the backend. Here's the OutputCache bit from the aspx page:
<%@ OutputCache Duration="86400" Location="Server" VaryByParam="person_id; section" VaryByCustom="CMSPosting" VaryByHeader="Referer" %>
I assume I'm doing something wrong here. Hopefully it will be obvious to someone who knows that they're doing. If you need more info, don't hesitate to ask.

C# - Browser Cache Clearable Via Code?
Sep 18, 2010I have a menu on my site that changes depending on whether the user is logged in or not. With browser caching, the menu "gets stuck" in either state and is confusing to users.They'll login, but the menu won't update because it's still cached in the unauthenticated state... and vice versa.How is this typically handled? Can we refresh the user's browser cache from our code? Or do I just not allow browser caching? (would rather use it, very nice bump in speed).UpdateHere's how I set client-side, browser caching in my asp.net mvc 2 app:
public class CacheFilterAttribute : ActionFilterAttribute {
/// <summary>
/// Gets or sets the cache duration in seconds. The default is 10 seconds.
