I built the asp.net website in release mode, set the debug flag to false in web.config, but still some of the webresource.axd and scriptresource.axd and javascript files are not getting cached. fiddler shows the status code "200" for these items instead of "304". what else I am missing to cache these files?
View 1 Repliescombining these type of files so that there are fewer http requests? Or for that matter any other tips on making them more efficient?
View 5 RepliesMy website is looking in the wrong place for the scriptresource.axd and webresource.axd. How do I point it at the correct subfolder? Or how do I set it so that scriptresource.axd and webresource.axd are stored in the root of the website?All the ajax is done within subfolders. The web.config is at the root of the website.
View 2 RepliesI have a site that uses the Ajax Control Toolkit that's been running for several weeks and a week ago all of a sudden users are seeing script errors. I'm getting 'Sys' is undefined errors, as well as 'object required' and other JavaScript exceptions. The site does not function because of this.
I checked the page source and looked for the WebResource.axd and ScriptResource.axd's and tried navigating to them directly by putting the URL in the browser. I got a 404 error - file not found. If I do the same in our test environment, it comes back and asks me if I want to save or open the file. If I open it, I see the JavaScript that I am expecting (from the Ajax Control Toolkit).
In our test environment, with the same code, everything works fine. This tells me there was something on the production server that's preventing this from working. About 4 days before this started happening, we found that some user documentation (PDF) wasn't being protected by Forms Authentication (we need only legitmate users having access to it) so we added a wildcard mapping in IIS with "verify that file exists" was unchecked, knowing that if it were checked, we'd have this problem. I had one of the network admins check this setting after this started happenig and he said that it was still unchecked. I asked him to remove the wildcard mapping altogether and I still see the same behavior.
I am certain that this isn't a coding problem; again, as it went through the QA process in our test environment, everything works perfectly. And after the last deployment to production three weeks ago, everything was perfect as well. We added the wildcard mapping (which shouldn't have had an effect) and four days later the site breaks. I've asked our IT department if any changes were made to the server recently and nobody says they did.
What settings does anyone know of that might be causing this, either server or application? I checked the web.config and all the sections are there that deal with the ScriptResource HttpHandler and HttpModules. In fact, the web.configs are identical between the production and test environment, so I know it hasn't been tampered with.
Is there any way to change the path of both ScriptResource.axd and WebResource.axd to a relative path (remove the leading the "/")?
View 4 RepliesIn my web application, I have used AJAX Toolkit and my .net version is 3.5. When I run the application and save the page, so many ScriptResource.axd and WebResource.axd generate which makes the file size 200 to 300 KB more big. After doing the same procedures mentioned in the above link, it was working fine as all ScriptResource.axd and WebResource.axd file is removed.
But when I go from one page to another page using on click, then Object Expected Error comes and when I debug it,I found one ScriptResource.axd file containing query string like .axd?d=-bA.like this and Request. GetResponse cannot find the file and it gives 404 errror (File Not Found).
I am developing a website in ASP.NET and I am using various javascript frameworks/libraries. The different files belonging to these frameworks/libraries rarely changes thus there is no reason to refresh those files once they have been sent to the client browser (atleast not everytime a page is served).I see that the HttpContext object can be used somehow, that I can set the content expiration on the files/folders on the IIS, or maybe setup somekind of caching in the web.config file. 1. What is best practice/what approach should I take
View 2 RepliesHow do i make sure that for particular ASP.NET page CSS/JS file will not be cached on browser side (each time its loaded from server)?
Anything that can be done using the server side code?
I'm having a problem trying to combine the ScriptResource.axd files automatically generated by Ajax using ScriptManager's CompositeScript property....on some pages there's 15 of these files, so I'd like to reduce that number to reduce the HTTP requests. I tried following the post here - [URL] - but am getting errors when trying to do what it instructs, such as:
Microsoft JScript runtime error: 'Sys' is undefined Microsoft JScript runtime error: ASP.NET Ajax client-side framework failed to load. Below is the code I am using for the ScriptManager. These errors go away if I do not use CompositeScript. Has anyone else attempted to combine these files? Am I doing something wrong in this code?
[Code]....
Google Page Speed is saying we should combine external JavaScript. Fair enough.
I know that the way to do this is to use a CompositeScript tag inside asp:ScriptManager.
<asp:ScriptManager runat="server">
<CompositeScript>
<Scripts>
<asp:ScriptReference Name="AjaxControlToolkit.Common.Common.js" Assembly="AjaxControlToolkit" />
<asp:ScriptReference Name="AjaxControlToolkit.Calendar.CalendarBehavior.js" Assembly="AjaxControlToolkit" />
< ... />
</Scripts>
</CompositeScript>
</asp:ScriptManager>
What I don't know is which script references to add. In my page I have lots of <script src="/ScriptResource.axd?d=big-string-here" type="text/javascript"></script>
How do I discover what <asp:ScriptReference Name="x" Assembly="Y" /> tags I should add to the CompositeScript tag? There's a usercontrol out there with this specific aim, and we even have already used it before, but I can't find it again o Google.
EDIT
The usercontrol I was looking for is ScriptReferenceProfiler. How to use it.
I've seen "What is an elegant way to force browsers to reload cached CSS/JS files?" but the answer there uses PHP and it doesn't address the fact that the CSS is injected dynamically by an ASP.Net Theme.
View 2 RepliesI have a web control and it needs to inject JavaScript content into ASPX page using RegisterStartupScript. But I don't see a way of doing so. If I use this.Page.ClientScript.GetWebResourceUrl it will return URL which can be used for RegisterClientScriptInclude, but I need the content of the file injected and not reference.
View 6 RepliesI have used a external js file for a upload operation in my page.. once the file get loaded in temporary folder, it gets loaded from there even if new changes are made the old version that exist in temp folder gets loaded... i have writtenResponse.Cache.SetCacheability(HttpCacheability.NoCache); on my page But it still loads the js file in cache. When i cleared the temporary files manually it works fine...But i cannot ask my client to clear temp folder,,,Is there any solution to load js file not from the cache, ie reload every time page is loaded...
View 2 RepliesWe 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)?
View 3 RepliesI used following to cache my ASP.NET page.
Response.Cache.SetExpires(DateTime.Now.AddSeconds(60));
The problem is when I send AJAX (XmlHttpRequest) request from other page to this page, that response does not get cached on any browser but IE. (On IE, it gets cached even if I don't specify). How do I make it cache?
I want to disable the broswer back button without using javascript. So far i have used this coding:
Response.CacheControl = "no-cache"
Response.CacheControl = "private"
Response.CacheControl = "public"
It's working fine in the internet explorer 8 but in case of mozilla fire fox it is not working.pls say same the solution to work in all browsers.
my project contain two config files. first config file in root directory, second config file in child directory
part of .config in root directory:
<httpHandlers>
<add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" validate="false" />

When 'ScriptResource' in root config file, all's well. But when 'ScriptResource' in child .config file. I have error "Error: 'Sys' is undefined".
I have ScriptResource.axd file which is use and whithout compression. also I have JavaScript files that are not compressed too.
this is making website loads reallu slow....20 seconds....:
What can I do to reduce this and compress everything?
i have made an .aspx page of c# in folder named as "USERPANEL". Also placed all my js in "js" folder and css files in "css" folder & all these pages are placed under "USERPANEL" folder same location where i have create a page. If i would placing the css on the page itself then it's working but not loading any external stylesheets. why? below is code as i am attaching the fontawesome file placed in fonts folder.
<link rel="stylesheet" type="text/css" href= "fonts/font-awesome.css" runat="server"/>.
Scenario: I have a complex Asp.net app serving various units through programmatically constructed control collections in HttpModules. Some of these controls use Asp.NET Ajax.
Across many different units, ScriptResource.axd averages a transfer size of ~27k.
I have a ceiling that only allows ~3k for it.
There definitely isn't time to retrofit all the Ajax functionality with jQuery or hand-rolled js functions or whatnot. We already have the .axd coming over with gzip encoding (uncompressed it's more like 97k). It's often cached, but that doesn't matter: I have to hit a hard, low, externally-imposed limit on first-request total transfer size... markup, scripts, images & all summed up a-la firebug. I've been avoiding the .axds, but there really isn't anywhere else to shave bytes, and I have 24k to go.
Possible approaches: I'm not yet using Asp.NET 3.5 SP1's compositescript functionality, but I figure that would only save on request/response headers, and I'm not even sure headers count against me.
I don't have any other ideas other than something radical, like creating a response filter that uses reflection & some dictionaries to figure out what js functions are actually needed, and only emit those. I could cache the resulting list for each unit, since I have a low response time ceiling as well, and I don't think the .axds change from one request to another. Is this feasible? Any other ideas? ...what if I buy beer for the hero with a solution?
I have setup my website (ASP.NET 3.5) with AJAX, running with no problems at all.
When I test my website locally and on my main top level domain, there are no problems.
When I'm on a subdomain page, AJAX client side framework fails to load. I observed the problem deeply and found that whenever I'm on a subdomain page, WebResource.axd DOES load but ScriptResource.axd DOESN'T load (returns 404 Not Found error). I think I should modify some entries at web.config file, but I have no idea on what to do?
