Scenario: I have a bunch of web applications for which I want to add a simple ping functionality via http handler. Example: [URL]
Problem: For some of the applications this approach does not work becasue of custom HttpModule. These modules have some depedency on either authentication or some other processing logic due to which it makes the request invalid.
I am trying to find a solution to get this ping functionality work without making any changes to existing HttpModules.
I am developing a web page that needs to display, in an iframe, a report served by another company's SharePoint server. They are fine with this. The page we're trying to render in the iframe is giving us X-Frame-Options: SAMEORIGIN which causes the browser (at least IE8) to refuse to render the content in a frame. First, is this something they can control or is it something SharePoint just does by default? If I ask them to turn this off, could they even do it? Second, can I do something to tell the browser to ignore this http header and just render the frame?
I create custom HTTP handler for auto generating file and I want to tell IIS7 to serve current request like normal static file because I need to use IIS and web.config file to control compression setting and any other HTTP header of current requested file.I know. there is an internal class called StaticFileHandler in ASP.net. But I cannot access it. Or you have any other way to work like this.
i redirect a page from http to https using http module begin request handler .i am calling webservice using ajax but it is saying webserice not defined .which otherwise works fineits work fine when rediect page in page_load instead .but i need to add function for https to http in every page. i still not know why ajax is not working when i use http module for redirect
We are using the Facebook API and receive back URLs for profile image thumbnails. Unfortunately the protocol is restricted to just HTTP and it doesn't support HTTPS. The page on our site that hosts the thumbnails is always delivered via HTTPS, and if we use HTTP for the thumbnails the user will receive security warnings from their browser.
Solution:
Build an HTTP Handler that "passes through" the image from the Facebook URL, but allow the handler to be called via HTTPS. Before I started coding I thought I could something like this:
but I ended up having to save the image to an object in memory than write the image to the Response.OutputStream using the image save function.
Current Code:
[Code]....
This seems inefficient but I can't find a way of using the HTTP Handler as I orginally intended. Is there way of accomplishing the goal without creating the image memory and just "passing through" the call?
I've tried to write my own HttpModule (IHttpModule) that adds a Header like that:
public class MyModule: IHttpModule { public void Init(HttpApplication c) { c.BeginRequest += delegate{c.Response.AddHeader("MyHeader", "MyValue");}; } public void Dispose(){} }
I have a scenario where my application is going to be publishing services that are consumed by both PC's and mobile devices, and I have a HTTPModule that I want to only perform work on only the mobile requests. So I thought the best way of doing this was to point the mobile requests to a different file extension and have the HTTPModule decide to process only if the request targets this new extension.
I don't need a custom HTTPHandler for the new extension; I want to program the services like a normal .ASMX service, just with a different extension.
First, can I do this? If so, how do I do it so that requests to my new extension are handled just like .ASMX requests?
Second, is this the right approach? Am I going about separating and managing the mobile vs. PC requests the wrong way?
I'm trying to write an HTTP GET handler. The path should start with http://site/processTask and have a set of URL-encoded parameters. I have the following in my web.config
now when I type the URL http://mysite/processTask in browser I get HTTP 404 but if I change the add verb line to the following one:
<add verb="GET" path="processTask.asmx*" type="MyHandler.ProcessTaskHandler, MyHandler"/> and type http://mysite/ProcessTask.asmx in browser the handler is run and I get the response from the handler. What's the problem? Why is the handler run only when the path contains .asmx? How do I change web.config so that .asmx is not required?
I've created a class library project and this has a class implementing the IHttpHandler interface. Let's call this class ZipHandler. Let's say the namespace is Zip. I want that whenever any Http request comes for a zip file, my ZipHandler should handle it, regardless of whether the request is to an Asp.Net application or a normal virtual directory.
Queries:
Is it possible (it should be given the hype about integrated pipeline etc. in IIS 7)? How to do it?
I am new to this topic. SO please look over my stupid mistakes. I have web application and its virtual directory path is as followshtpp://localhost/TxtXmlImggHandler/This root has three pages one for text, one for xml, one for images. Actually these pages call three different handlers. I had no problem when I send/receive some data to HTTPHandler for processing, had no problem when I request xml file from HTTPHandler.Now I am trying to get image from HTTPHandler, but no luck. All my HTTPHandlers are sitting in root of my web application
I successfully added and configured HttpHandler in an Asp.Net WebApplication, but facing problems while trying to add same HttpHandler to Asp.Net WebSite. I have registered it in the web.config, am i missing something This is the error I am getting Configuration Error
Description:
An error occurred during the processing of a configuration file required to service this request. Parser Error Message: Could not load type 'MyHandler'.
Line 98: </pages> Line 99: <httpHandlers> Line 100: <add verb="*" path="*.result" type="MyHandler"/> Line 101: <remove verb="*" path="*.asmx"/>
Here is handler
public class MyHandler: IHttpHandler { #region IHttpHandler Members public bool IsReusable { get { return true; } } public void ProcessRequest(HttpContext context) { } #endregion }
NOTE: I have not made any request for the handler via url, it is just not letting me run application.
dim filepath as string = "http://order/venommain.asp?f=N&username=0E3706&password=0E12Y6&docs=-1&folders=-1&sv=&e=-1&nw=&q1=TITLE+CONTAINS+PDFFILENAME"
response.redirect(filepath) // it works and open PDFFILENAME
But,
System.IO.File.Exists(filepath) alway return false (it should return true)
How to code to detect the file existing in http format?
In my MSSQL Server I have a table named Nomogram including an attribute named Img1 which include an image of type varbinary(MAX)I wish to load that image on my webform using an http-handler (ashx).How do I do that? I have looked at this sample but I can figure it out how to solve my exact problem. [URL]
UPD: Seems like the cause of problem is that HTTP handler response isn't caching on server. The following code works well for web-form, but not for handler:
I want to use HTTP Handler in order to create a RSS feeds. For the purpose, I want to put my logic for creating the rss XML in C# class, which implement IHttpHandler, then to "map" this handler into the web.config file and to register the "mapped name" in my routing rules. I am doing something like this:
public class RSSFeedHandler:IHttpHandler { public void ProcessRequest( HttpContext context ) { [code]...
I have the next problem: I need to process only 1 request at a time from each user. Lets assume that server identifies each user be UserID, sent in query string.cHow can make the server work the way like FIFO (do not start processing next request until the previous is fully processed)? Should I use the named mutexes inside HTTP handler and assign the name to mutex by UserID?
i have an ASP.NET 4.0 HTTP handler that should receive and send data in json format. I'm using jquery to send json objects serialized in a string to the handler. It correctly sends the request but i don't know how i could retrieve the data from the httpcontext passed to the handler and how i could deserialize it..
the purpose of this HttpModule? It's showing up on my HttpModuleCollection list, but I don't know what's it's for.System.ServiceModel.Activation.HttpModule
I'm just reading about implementing my own HTTP handler for ASP.NET 4.0 and IIS7. This looks really cool. I want special processing for ZIP files and it seems like an HTTP handler is the perfect solution.However, what's giving me trouble is that the handler must be in a separate assembly. So how can I access the rest of my application from this assembly?Specifically, I'd like to determine if the user is authenticated and redirect them to the login page if they are not. But User.Identity.IsAuthenticated, etc. will not be available from my handler.(Yes, I know there are ways to approach this without an HTTP handler but they don't seem appropriate for my specific needs.)
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?
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?
