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:
I'm using a HttpHandler to intercept PDF file download requests and modify the PDF file. I'm stuck on what to do if the requested file doesn't exist on the webserver. If I handle the Exception and return an empty response, it gives the user a 0 byte file to download. If I ignore the Exception, then ASP.NET catches it and the user is redirected to my unfriendly customError page.
The default behavior of a [WebMethod] attributed static method on an aspx page is to return the error to the caller. We are accessing these methods using json, and the only way we have found of capturing exceptions is either a try/catch in every webmethod on the site or using a javascript callback with the error (which has the unacceptable downside of exposing the error to the client).
Is there any way to globally handle these exceptions using the HealthMonitoring setup in ASP.NET?
I created a HttpHandler for downloading files from the server. It seems it is not handling anything...I put a breakpoint in the ProcessRequest, it never goes there.
public class DownloadHandler : IHttpHandler { public void ProcessRequest(HttpContext context) { //download stuff and break point } }
It never stops there, as mentioned. I also registered it in the web.config.
I am not sure about the path part of that entry. What do I have to enter there? I am downloading txt files, but the URL does not contain the filename, I somehow have to pass it to the handler. How would I do this? Session maybe?
I need to access image files (.jpg) on a server other than the web server my app runs on. I would like to use an httphandler to do this but I am unsure of the syntax to specify the path. I have tried mapping a drive on the web server to the file server but that didn't work. I have tried using a UNC path but that did not work either.
I have a problem with large respones and IIS7, the server runs out of memory. I've written the test code below that works pretty much like my real code... When i start to download the file i can se the memory usage rise until it hits 100% and Firefox complaints about lost connection to server, looks like IIS7 does not release cache or something.. Works in IIS6 by the way
I am building an application that allows a user to upload multiple images, resizes them, and saves them. What I need (ok, what I'd like) is the following...
I would like some sort of way to prompt a user to crop the photos after they have been saved. I have code that creates a 175px square rectangle and saves that image. I need the user to select the image section they want saved and to do so I envision a window that automatically prompts them to do so once the upload(s) have completed. I think my preference would be to have a page or control (datalist, repeater, ectc..) that refreshes every time an image is saved and allows the user to crop the newly saved images. I'm opened to advice, opinions, free drinks and a clue.
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.
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.SetCacheability(HttpCacheability.Public); Response.Cache.SetMaxAge(new TimeSpan(1, 0, 0)); }
I just want the url /style/style.css to point to another static file on the webserver..
I'm getting this error:
There is no build provider registered for the extension '.css'. You can register one in the <compilation><buildProviders> section in machine.config or web.config. Make sure is has a BuildProviderAppliesToAttribute attribute which includes the value 'Web' or 'All'.
I need the user to be able to upload multiple files to my server, thus I am using the SWFUpload utility. SWFUpload sends the files one by one, and I need to store them all in the same temporary directory. My ASP.NET handler recieves the files one by one and I can store the file appropriately.
My problem is: How do I know which files belong to the same upload? Rephrased, how do I connect the files in my handler?
I have one aspx page and more than ascx files, i have links on aspx page. if i click one of the link, it will upload the relevant ascx file on main aspx file.
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?
I am new to MVC. I am using MVC and VS2010. I am trying to publish my website to a remote server. All files are copied except some static pages i have kept inside a folder. for e.g. i have a folder named Content. I have around 5 .pdf files inside this folder and also a .css. When i do Build->Publish <appname> all the files including the .css is copied but not the .pdfs.
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?
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.
Our old ASP.net site stored static images in a sub directory on the root called /images.
Our new ASP.net MVC site stores these images in the new layout of /Content/Images
I've changed all the pages in the site to cope with the new folder structure, but I'd like to set up Permanent Redirects from the old static images to the new location.
We're having the same setup and receiving the same problem as:
[URL]
Setup 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.
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.
Does precompilation have any effect on XML files? i.e. can I obscure/protect xml files using precompilation? I assume that it has no effect as they aren't code.
If I use XML files as Embedded Resources, they appear in the DLL in a text editor as normal text. If the dll is edited and saved using a text editor, will it still work if it is unsigned?
