JQuery :: Validate Request And Web Handler(ashx)

Jun 24, 2010

I have a webpage where I am displaying some data.

On the top of that I have a button. On click of this button I am calling my webhandler using jquery/json, passing in some data to this handler. Now this data can containg html tags. So whenever I try to click that button it gives that Potential threat script

error. So I thought let me include ValidateRequest = false to my webpage.

Now when i do this it never hits my handler. I tried to debug also but my breakpoint is never hit in my handler. How to handle this.

This is how I call my handler:

where hidden value is the value which I want to pass to my handler and may contain html tags..

Caching - Call A Page (ashx Handler) From A Different Page?

Jul 12, 2010

I have a admin page in asp.net that adds data to a database. This database is available as a JSON string to external websites, however, since it's a lot of data, the external websites cache this data locally.I want to be able to ping the external websites to let them know the data has changed so they can referesh their cache. I figure I can setup an ASHX handler that receives a parameter telling them what data has changed, so they can both delete that data and refresh it.The only part I'm not sure about is the best way to call this external page from my admin page. Do I just do a regular WebRequest and discard the result? or is there a simpler way to call a page from code when you don't need the response?

ASHX Handler; Fires Up Only Once?

Jun 23, 2010

I've got a simple ASHX handler that returns an dynamically generated image; the image is generated from a custom created class, and an object belonging to this class is passed to the handler using Session (I'd rather avoid using QueryString).The handler is used as the URL of an image on a ASP form which is very simple: a drop down list, a button and an image. Basically, depending on what the user selects from the list, the appropriate image will be generated once the button is pressed.

At the start the actual image has it's Visible property set to false; I don't want the handler to display anything before the data is all there.Once the button is pressed, the required Session parameter is added containing the necessary object, and the page is refreshed using Server.Transfer. When the Page_load method detects that the Session parameter has been correctly set, it sets the Visible parameter on the image to true.After that the handler fires up and generates the image.

So far so good... However, if the user now picks something different from the list and presses the button, despite the correct object being passed in the Session, the image won't be updated. In fact, the handler won't even fire up (if I put a breakpoint in there). I need to close the browser window and reopen it for it to work.Any ideas what could be the cause of such behaviour?I suspect the answer is very simple, and I just don't know something fundamental about ASP (or handlers)...

Disable Gzip For Just One Handler .ashx?

Sep 14, 2010

I am running a website using IIS6 and i wrote a simple generic handler which return smaller images when it receive image url as query string. My problem is that the server is applying gzip to some file types such as .aspx and .ashx. And that made my response image from the handler appear with lower quality because they are compressed.

How can i disable gzip for just this handler file, i hope for a solution without editing the IIS.

Send Data To Ashx - Handler But Not Query String?

Dec 22, 2010

I would like to open some page from external web-application in iframe. Usualy, I would indicate URL for iframe like this: URL = [URL] BUT. I need to send not only 'ID=12' parameter. I need to send a lot of data to handler in order to be processed. Usualy I do it by following code:

Dim wrq As WebRequest = WebRequest.Create(Data_WS_URL) wrq.Method = "POST" Dim postData As String = "PubmedIDs=" & vInput wrq.ContentType = "Application/x-www-form-urlencoded" Dim byteArray As Byte() = Encoding.UTF8.GetBytes(postData)

But when you use this code - you recieve response from webrequest as some amount of data - text or binary. I may write this respone to the place on the page where I wanted to have iframe. But response cannot always be accaptable. (for example - I render asp:Treeview by ASHX handler - when I do to ashx page - it renders well, collapse-expand works fine; but if I write web-response of ashx page as text/html - then there's something wrong with javascript, tags ids and collapsing nodes). And webresponse cannot be represented as as URL. How to combine this two approaches

1) Clear URL which can be set as source for iframe
2) Extra data for web-request, larger then QueryString can handle

Web Forms :: Proper File Serve Of An ASHX Handler

Apr 30, 2010

For our application we provide users with file downloads that utilize handlers to serve the files. Currently, the way it is served to the user is through window.location. When using this, at times, it causes issues under IE8. When an error occurs, it cannot be caught under the page that called it.


A) Is there a way to serve an ashx file handler to the user where the page that called it can catch any exceptions made from thje handler
B) What is the correct way to serve the handler, eg. window.open, window.location, etc. Would return false at the end of the javascript solve this? Are there any other ways

Is it possible to determine the HTTP protocol version (e.g. 1.0 vs. 1.1) used for a request within a .ashx handler? I can see all of the header information except for the version in Request.Params.

If not, what avenues are available to discover the HTTP protocol version when processing an HTTP request in ASP.Net?

Mar 25, 2011

We are providing downloads of our application setups through an ASHX handler in ASP.NET.

A customer told us he uses some third party download manager application and that our way of providing the files currently does not support the "resume" feature of his download manager application.

My questions are:

What are the basic behind resuming a download? Is there a certain HTTP GET request that tells me the offset to start at?

Configuration :: Web Setup Does Not Install Generic Handler (ashx)

Jul 21, 2010

I've created a Web application (VS2008) that contains a single Generic Handler (handlername.ashx) and a web.config. I've also added a Web Setup project to use for deployment that uses the primary output from the Handler project. Install works without any errors and all the referenced DLLs are installed in the target location, with one issue. It doesn't install the ASHX file or the web.config.

Publishing the web app to the target location works as expected (includes both DLLs and the ASHX/Config files).

Is there something specific I need to do for the Web setup to include the ASHX/Config files?

ASHX Image Handler Lets Document.ready() Fire Twice

Nov 1, 2010

I got a $(document).ready() handler in my aspx page that fires twice. I trapped it to the follwing line of html (this line is part of the itemtemplate of a listview):

<img src='Images.ashx?Url=<%# Eval("Url")%>&Type=3' alt=''></img>

Seems that using the images.ashx is causing my problem, putting a 'normal' url as src gives me no problems.

It must be because the handler is called, but why is loading an image giving a second fire on $(document).ready()

It is only in IE8. Chrome, FF and safari work as expected.

HttpHandlers / Modules :: .aspx Sessions Being Called In .ashx Handler?

Aug 20, 2010

I have an Handler.ashx file and on .aspx page load it calles the .ashx file for image reading. I am attempting to pass a session from the .aspx file to the .ashx file in order to make my query of grabing the image secure. The problem is that everytime I call a session: HttpContext.Current.Session["ID"], the value is returning null or errors saying the o so commong "Object reference not set to an instance of the object". I have tried a couple ways of grabing the session:

1.) context.Session["ID"]
2.) HttpContext.Session["ID"]
3.) HttpContext.Current.Cache["ID"]

none of them are giving me the ID session set in the .aspx page. should i be using Server.Transfer instead? is there a way to grab a session variable set in a .aspx page and called in a .ashx page?
