i recently made a website and have uploaded it to a hosting server. After i had completed the website i noticed that i never added in any expiration onto the files/images plus that i dont know how to do this outside of IIS. As i dont have access to the IIS on the server i need a way of embeding code to set a short exportaion on the images and xml files cached. whats the best way of doing this?
View 5 RepliesI've been trying to get image caching working for the last 8 hours and I keep the same problem time and time again, I'm trying to cache Images at the moment and then when thats succesful, apply this to cache my js and css files. I have at the moment Sql Dependancy caching working on my dynamic pages but the page still takes to long due to images not caching.
What I have tried is going to IIS7 Management and adding HTTP Response Header for the images folder and setting various things for the cache control.i dont care how long it caches it on the client or on the proxy servers i just would like it to check when the file was modified and compare it with the one in the client or proxy cache and if they are different then fetch the new image which has been ftp up. i could solve this by changing the image name but the thing is the image name is generated when they are ftp'd to the site by an application and the name is a direct reference to the product so i cant change the name each time, as it would mean making a lot of otherpages accross the board.
so What i would like, is to set and expiry date of lets say 32 days or more on the images and then check to see if they have changed by date modified or some other way of checking(Etags maybe) I'm not sure, if they have changed on the server then redownload and recache them, I tried using post-check and pre-check together but that just permantly cached them, so when i change the image the only way it would display the new image is to just hit F5.
In Brief, how can i Cache images, on the client machine/ proxy cache and recache them when the modified date of the file has changed.
I want to implement the functionality like below.
1) Use AdRotator to view the Ads.
2) Change Ads on every 15 sec.
3) When user is on page where Ads are displayed now user clicks Back-Forward and come back to that page. This time if user come back within 15 sec. Same image will be displayed and no money will be diducted for that. So here I will need to show Image from cach.
4) Only once load images from server. For each other cycle to display images fetch it from cach.
I have difficulty in implementing Steps 3 & 4.

View 4 RepliesI have gotten confused about how page caching works in ASP.NET. Suppose a user has navigated to "home.aspx" on my website and say I release a new version of that page to the server and the user subsequently navigates to that page, he will get the updated version, is that correct? Is there ever a case where I need to be concerned that the user is NOT getting the latest version of a page(or code-behind) file? The reason I am confused is that quite sometime ago, I found the following code to put in my Page_load event to prevent page caching:
[Code]....
But the more I think about it, I cannot remember the rationale behind this. Whenever I do a release and subsequently visit my site, there is a noticable delay as ASP recompiles. So now I am wondering why the above "no caching" code would be needed or when it is appropriate to use.
I want to use caching technique for .js,.css and images( to avoid round trips and to improve performance of page load) .So, on IIS 7 using Http Response Header, i set Content Expriation to 7 days.Now, on browser its caching which is avoiding round trips for static content ...which is good sign.Now, i modified one of the .js file and i deployed that .js file on server and due to caching my new code is not reflecting on client machines .So i tried lot of ways and here is what i tried after deployment of new .js file After deployment of new .js file
1) I manually delete all the browser cache(cookies,urls,forms,page content etc) on internet explorer
2) used ctrl + f5 to get refresh
3) again on IIS i went back Http Response Header section and set Content Expriation to never
4) stopped the website and restarted
5) on web.config file tried this only
<staticContent>
<clientCache cacheControlMode="DisableCache" />
</staticContent>
6) Also tried to set this on .aspx page
<HTML>
<HEAD>
<TITLE>---</TITLE>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
</HEAD>
<BODY>
7) tried to set this on .aspx.cs file
<% Response.CacheControl = "no-cache" %>>
<% Response.AddHeader "Pragma", "no-cache" %>
<% Response.Expires = -1 %>
My target browser is IE.None of them worked,Finally i renamed my .js file to different file name and changed code to make use of that new .js file ..but no luck on this too .Because what i set intially for 7 days still my client machine remembers that.
How do i tell IIS server to refresh cached content code , when some thing got changde on .js or .cssfiles?
i have implemented an image preloader using javascript inside my mvc 2 web app, in order to display an animated "loading" image .gif while sequentially displaying page images.I have also implemented caching using a cache profile for the controller action that displays the specific page ([OutputCache(CacheProfile = "LongCache")]).The problem is that the image preloader javascript is called when caching is applied. I was wondering whether i could, somehow, use the image preloader code only when the page gets refreshed and not when the cached version is rendered.
View 2 RepliesI use a Masterpage (asp.net webforms) on my site and I woluld like to implement caching of some static files, like javascript, css etc.
I've tried adding the following to my page_load (in the masterpage) but when I use Fiddler the static files are still under "no-cache".
protected void Page_Load(object sender, EventArgs e)
{
// Set cache for 1 hour on all computers and servers.
// ... Proxies, browsers, and your server will cache it.
Response.Cache.SetCacheability(HttpCacheability.Public);
Response.Cache.SetMaxAge(new TimeSpan(1, 0, 0));
}
What am i doing wrong here?

View 2 RepliesI have an ASP.NET master page which references a #include file as follows:
<!--#include virtual="/includes/scripts.inc"-->
I have modified the file /includes/scripts.inc but the changes do not show up in pages. What needs to be done so modifications will be reflected? I need to avoid the following: restarting the server restarting IIS modifying web.config (doesn't appear to have any effect)
pretty much anything that causes the app domain to restart Any other options? Is there a setting which affects how long IIS caches #include files?

View 1 RepliesAt some point in the last month, two web application projects that I've been working on have stopped showing updates to aspx and ascx files until IIS is restarted, or the website they belong to is reset. This seems to be very random and I can't find any reason in the web.config sections that would cause this change. What are some good places to look for a source to this issue?Current caching parts of web.config: Removing the outputCacheProfile and restarting IIS made no difference.
<caching>
<outputCacheSettings>
<outputCacheProfiles>
<add name="ClientResourceCache" location="None" enabled="true" duration="3600" varyByParam="*" varyByContentEncoding="gzip;deflate"/>
</outputCacheProfiles>
</outputCacheSettings>
</caching>
Commening out the staticConent and restarting also made no difference
<staticContent>
<clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00">
</clientCache>
</staticContent>

We've also tried adding .ascx and .aspx extensions with CacheUntilChange which made no difference. Other sites with these same settings aren't having the issue. Edit: Originally this state that there also was no update when the project was built, I haven't personally been able to confirm that issue but was told by another developer that was occurring.

View 2 RepliesI'm busy trying something new, I'm currently busy experimenting with asmx web services, jquery for ajax requests to the web services and jtemplate as a client side template engine. Everything works fine so far, my only problem is authentication. I'm using forms authentication with a regular login.aspx web form with login control added as my login page. My content pages that needs to be authorized are .html files. I found a wiki article on howto add mappings to the aspnet_isapi.dllfor other file extensions, it is based on IIS 6. Does anyone know how i get this working on Win 7 IIS 7.5? I tried various things inetmgr with the mapping handler without success, the closest i got was when it did redirect me to login page, i logged, it directed me back to the html page but it was blank.
For that I used "add managed handler", request path = "*.html", type = "System.Web.UI.Page, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" name="HTML"

I am working on my first ASP.NET Website using VWD and C#. I did some inital design with Expression Web 4 such as created a master page with 2 content place holders, 2 style sheets 1 for the layout and 1 for the nav menu, and some images in a folder. I started with an empty ASP.net site opened my masterpage and saved it to the VWD directory. Now my Solution Explorer contains a MasterPage and a webconfig .cs file. I would like to import the style sheets and images I mentioned earlier but I am not sure how to accomplish this. do I have to open and save as all these items or can I impot them? Do I use the ADD NEW Item command?
