Which plugin is used on this website to download files? is it PHP coding?
https://freesvgdesigns.com/life-is-short-lick-the-spoon-free-svg-files-1593/
This is difficult to say exactly what method they are using but it looks like a JavaScript pop-up that appears with the ad which then makes an AJAX call to download the file when the close button is clicked. Unless you already have clicked the ad before in which case it looks like an AJAX call to the download page which has download headers set.
Again, difficult to say exactly how the server is working, but this is how I would have done it and it looks similar in functionality.
I suspect that this may not be a plugin at all by the way. It's just standard HTTP processing.

I'm trying to implement an upload with progress bar code i found here. But when i run my example code i get the following error in IIS7 Windows7:
Click here for larger image
I tried messing with my handlers but only messed it up more as i don't know what i'm doing. Can someone help me get this working?
It appears that your are trying to upload the file to (or trying to get process update from) a html file (fileupload.html) - now html files are considered as static files by IIS. So you can only issue GET request (there is no point in submitting POST to a static file because the content is not going to change based on POST data) and hence the error.
Perhaps, you have done integration incorrectly or may be using wrong plugin (the author is talking about using it in conjunction with apache module). You may want to look at alternatives from below links:

File Upload with progress bar in Asp.Net Mvc/ jQuery?
I have a web form that requires users to fill out some information and upload an image.
What I don't understand:
If I use uploadify to select a file doesn't it upload it right away to the server? Is there a way to defer that until the user would click on a form submit button? Or at least not save it to the file system?
Most examples use a custom HttpHandler for uploading files, but my file upload is part of a form. Should I still use a HttpHandler for that?
Well, I'll try to answer all your many questions, one by one. But before anything, open the official documentation because I will rely on it for answers.
If I use Uploadify to select a file doesn't it upload it right away to the server?
As you can see on the first demo, you can have a anchor (or a button or anything) to trigger the upload start. The Uploadify don't upload nothing until it's done (if the property auto isn't true).
Is there a way to defer that until the user would click on a form submit button?
Like described above, yes. And it's the default way (since the default value of auto is false).
Or at least not save it to the file system?
While the button doesn't trigger the .uploadifyUpload() method, nothing goes to the server. But when the Uploadify starts sending, it will be handled by the server (with the HTTP Handler). The handler is the guy that save it to the file system.
Most examples use a custom HttpHandler for uploading files, but my file upload is part of a form. Should I still use a HttpHandler for that?
As described on the script property, you can point to any server-side language that will handle the HTTP Request containing the data. The HttpHandler is the right thing because it haven't any other processing before or after the code you write. It isn't hard. The official forum shows some samples. And here on StackOverflow we have many questions about it, like these: Getting Uploadify Working in C# and Uploadify not working with ASP.NET WebForms.
The server shouldn't save the file until it is actually actioned by a handler. The Uploadify is providing the UI control for the gathering of the files and feedback. There are some settable properties available to control whether you want the "Auto" upload behavior or not.
You still need some king of server side processing for saving the data and an HTTPHandler is the usual way to do it. The HTTPHandler just operates on what file information it gets from the browser as part of a multi-part form data.

Hii,
Any one knows how to upload files to the physical location of the server. It is possible using file upload control that i know. But i want to avoid the external postbacking of the page. For e.g exactly like what in the yahoo mail did.
In yahoo mail latest version if you attach a file that won't post back and attach that file in to server. What is the technology behind that?
Normally when you submit a form it does a POST request to the server, causing a refresh. Ajax requests get round this by using JavaScript to send the POST data through to the server, and that doesn't need a page refresh.
Ajax requests can't be used to send file data though, so the best way to currently do it is with an iframe hack - you use JavaScript to dynamically build up a form within an iframe, submit that form via JavaScript, and listen for the iframe's onload event. So you know when the form has been submitted. A version of this approach is detailed here:
http://www.webtoolkit.info/ajax-file-upload.html
Other methods to do this would include using a Flash-based solution like http://www.swfupload.org/ or a wrapper like http://www.plupload.com/ - these will prevent you having to roll your own solution and will also provide some extra functionality - upload progress feedback, for example.
I do not really understand how Google Code handles file versioning.
I am building a jQuery plugin that anyone can access. Like so:
<script type="text/javascript" src="http://jquery-old-browser-warning.googlecode.com/files/jquery.browser-warning.js"></script>
This script accesses other files on the same project (via ajax).
The problem is, that when I upload a new file, it just seems like there aren't any changed to it. Google recommends that new files should have new names.
But then I would have to change the filenames that the script loads.
But then I would have to change the script file as well, and that would break everybodys implementation (with the script-tag above)
Is there a way to force a file to change when uploading with the same filename?
PS: If I go directly to the project page's file list. Then I do get the file with the updated content. But as I said, not when getting it through ajax.
The cheapest trick in the book to prevent caching is adding some random content to a GET parameter:
www.example.com/resources/resource.js?random=1234567
You can for example use the current timestamp for this.
This, however, causes any and every access to re-fetch the content, and invalidates any client-side caching mechanism as well. I would use this only as a last resort. If Google are that stringent about caching, I'd rather develop a workflow that allows for easy renaming of files.
I don't know your workflow, but maybe you can work with versioned directories?
Like so:
www.example.com/50/resources/resource.js
www.example.com/51/resources/resource.js
that would keep whatever caching the client employs intact, but whenever there's a change from your end, the browser would reload the content.
I think Its just a cache on the browsers, So when you request file from ajax, just add random parameters or version number.
For example, Stackoverflow add version parameter to static contents like
http://sstatic.net/so/all.css?v=6638
Are you talking about uploading files to the "Downloads" area? Those should have distinct filenames, for example they should be versioned. If you're uploading the script code, that should be submitted by the version control system you're using, and should most definitely keep the same name across revisions.
Edit: your code snippet didn't show up on my page, misunderstood what you're trying. Don't imagine Google would be happy with you referencing the SVN repository every time some client page is loaded :)
I am trying to find out how to upload a file from a web user to a server using an ASP page. The displayed page has an Input tag of type "File" like this:
<input type="file" name="uploadfile">
And a submit button that passes the Form info to another .ASP page. This page must take the path it gets from the Input control and use it to somehow save the file to the server.
I keep thinking there must be a common way to do this, since I see this kind of thing on a number of websites, but how is it done? Is there some sort of server object that can be called for it?
This script will help you.
Also, you may google for "asp upload file" - there are tons of results.
If you are doing any serious uploading or have a commercial product you really need to use a COM component in classic asp. Check out SA-FileUp. It has been the defacto standard for this since like forever.
If your hosting service doesn't allow you to install components, you may also want to look at this script:
http://chris.brimson-read.com.au/index.php?option=com_content&view=article&id=6&Itemid=7
I've seen a wide variety of upload scripts floating around, and they ... vary ... in quality. I've not used the script in the selected answer, but its worth trying a few different options.
I can recommend SA-FileUp and Dundas Upload. They both are easy to install and have good tutorials on how to implement.
