AJAX JavaScript Files Served From A Static Location?

Jan 5, 2010

I realise that this is going to be a fairly niche requirement and will almost certainly raise a few "WTF's" but here goes...

Within an ASP.NET Webforms application I need to serve static content from a local client machine in order to reduce up-front bandwidth requirements as much as possible (Security policy has disabled all Browser caching). The idea is to serve CSS, images and JavaScript files from a location on the local file system referenced by filesystem links from within the Web application (Yes, I know, WTF's galore but that's how it is). The application itself will effectively be an Intranet app that's hosted externally from a client but restricted by IP range along with standard username/password security. So it's pretty much a hybrid Internet/Intranet application but we can easily roll out packages of files to client machines. I am not suggesting that we expect nor require public clients to download packages of files. We have control to an extent over the client machines in terms of the local filesystem and so on but we cannot change the caching policy.

We're using UpdatePanel controls to perform partial page updates which obviously means that we need to Microsoft AJAX JavaScript files. Presently these are being served (as standard) by a standard resource handler within IIS/ASP.NET. Ideally I would like to be able to take these JS files and reference them statically from a client machine, and no longer serve them via an AXD.

My questions are:Is this possible?If it is possible, how do we go about doing so?

In order to attempt to pre-empt some WTF's the requirement stems from attempting to service a requirement with as little time and effort as possible whilst a more suitable solution is developed. I'm aware that we can lighten the load, we can switch to jQuery AJAX updates, we can rewrite the front-end in MVC etc. but my question is related to what we can quickly deploy with our existing application architecture.

AJAX :: Calling Non-static Methods From A Static Method?

Jun 30, 2010

I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.

I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.

For example, my Default.aspx contains a method LoadProducts().



This cannot change. There is no way to convert Business and Data layers to static.

How can I call the LoadProducts() method using ASP.NET Ajax?

AJAX :: Too Many Javascript Files Loading?

Sep 28, 2010

I recently ran yslow on a page i have (master paged etc) and it returned that there were far too many javascript files included (most of which I haven't added).

I guess my question is that given i have v1.0.20229.0 of the toolkit.dll (over .net 2)

I'm wondering if subsequent releases have fixes for this sort of thing?

AJAX :: Modifying JavaScript Files In The AjaxControlToolkit?

Jan 19, 2010

I have downloaded the source code for the latest version of the AjaxControlToolkit and have noticed that there are differences in the scripts included in the solution.

Previously, only one debug version of a JavaScript file was included for each control. This was then stripped of newlines and comments before building in release mode to embed these modified files in the output dll. However, now the solution has both the debug.js and .js versions (debug and compressed versions, respectively) included in the solution for each control.

My question is, if I desired to make changes to the debug versions of the JavaScript file for any control, does the compressed version of the file get generated automatically or is there some manual action I need to take to produce those files? It appears as though with this solution there are no integrated build tasks as in the previous versions so I feel like my latter suspicion may be correct but was hoping for input from somebody who knows more about this.

I do not like the idea of including overriden methods of toolkit funtions in my site's JavaScript, I am just curious how I would go about producing the release version of the script. In other words, how would the developers that work on the AjaxControlToolkit do this when working with the solution.\ | m ny;[6n n

Download All Csv Files From An Sftp Location?

Oct 12, 2010

I need a program that would download all csv files from an sftp location. I've the sftp host IP, user name, password and port details of the sftp location. I am able to login through Filezilla. But as I need to login programmatically, so that I can get a list of all files in the folder.

When the code works fine for a ftp request, it doesn't for an sftp request. Given below is my code to connect to the ftp uri.


My system admin says that there is no uri that could be given for sftp sites at all. Now, how can I go about this? Is there any third party tool available for this?

Necessary To Manually Cache Static Files In C#?

Nov 29, 2010

I have a class that is creating an instance of StreamReader to an xml file on the local filesystem.
It may be possible that this same file is requested multiple times per-second.

I was wondering whether I need to manually add this file to the System.Web.Cache and read it from there, or whether Windows itself is clever enough to cache the item itself so that it 'knows' when ASP.NET requests this file the second/third etc time that it doesnt have to do a disk seek/read operation and pulls it from its own cache?

This article: http://dotnetperls.com/file-read-benchmarks seems to back this up, but this: article:

[URL](although not discussing from a performance perspective, and maybe for other reasons entirely) lists how to add a physical file to the cache.

C# - How To Implement Caching Of Static Files

Mar 15, 2011

I 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.SetMaxAge(new TimeSpan(1, 0, 0));

How To Protect Static Files With Form Authentication On IIS 7.5

May 25, 2010

I have a website running on a IIS 7.5 server with ASP.NET 4.0 on a shared host, but in full trust.

The site is a basic "file browser" that allows the visitors to login and have a list of files available to them displayed, and, obviously, download the files. The static files (mostly pdf files) are located in a sub folder on the site called data, e.g. http://example.com/data/...

The site uses ASP.NET form authentication.

My question is: How do I get the ASP.NET engine to handle the requests for the static files in the data folder, so that request for files are authenticated by ASP.NET, and users are not able to deep link to a file and grab files they are not allowed to have?

Wildcard HttpHandler Not Handling Static Files?

Jan 26, 2010

I had a look through some of the older questions, but I can't find anything.I have a Wildcard HttpHandler on my web app which is processing the url and working out if it can do anything with itIf it can't, then the StaticFile Handler should pick it up and just serve it as a static file (like an html file).The problem is, it's going through the Wildcard handler, then seemingly not going to the StaticFileHander. Is there something I need to do to the Wildcard handler, or in the web config?This is my web.config:

<add name="Wildcard" path="*" verb="*" type="Rewriter.RewriterHttpModule"
modules="IsapiModule" requireAccess="None" allowPathInfo="false"
preCondition="" responseBufferLimit="4194304" />
<add name="StaticFile" path="*.*" verb="*"
resourceType="File" requireAccess="Read" allowPathInfo="false" preCondition=""
responseBufferLimit="4194304" />

MVC :: BeginRequest Event Fires For All Static Files?

Oct 29, 2010

I was under the impression that static files (CSS, images, @font-face files, etc) bypassed ASP.NET completely, and were served directly by IIS. However, my BeginRequest event handler is being called for every HTTP request, including those for static files. This concerns me because I'm creating an Entity Framework data context to be used for the lifetime of each request in that event handler. I don't want to create those contexts if they're never going to be used.

I'm using IIS 7 on Windows 7 Ultimate with so special handler mappings defined. Do I have it wrong? Should these events be firing?

Disable Website To Respond Request Except Static Files?

Nov 2, 2010

I have 2 website on my IIS which have the same physical location on disk. Example:

www.xxx.com path on disk : c:wwwxxx.com
img.xxx.com path on disk : c:wwwxxx.com

I want that img.xxx.com only response for static files like images, css and js files.

My main goal is to serve static files from a cookieless domain (using img.xxx.com for cookieless requests). But if I write img.xxx.com to browser i see the same content with www.xxx.com. I want to block all request to img.xxx.com except images, css and js request.

I don't want to set another folder for img.xxx.com because it is very hard for me to change all images url to new url.

Setup IIS 6 To Only Server Static Files From Virtual Directories?

Jun 21, 2010

We're having the same setup and receiving the same problem as:


Server 2003 32bit, IIS 6
ASP.NET wild card mapping

A virtual directory mapped to an UNC share serving static images for a CMS in a load balancing environment

My question if it's possible to turn off asp.net from virtual and only serve static files e.g. images in the virtual directory, to avoid the problem with too many open connections?

If it's not possible I'll guess I have to implement a solution like [URL] to server the files from a local disc.

I found a possible solution at [URL] that removes the wild card mapping and makes it possible to turn of execution of asp.net files.
