I have a IHttpHandler that acts as a source to a jQuery Autocomplete input field. In the constructor of the handler I generate an index that remains fairly static between request (needs to be rebuilt maybe once a day).How can I cache the the index between calls? Debugging indicates that the constructor is called for each request. I've set IsReusable to "false".
View 2 RepliesI have the following Page_Load function...
protected void Page_Load(object sender, EventArgs e)
{
XmlDataSource1.Data = GetXmlFromFile(Request.QueryString["file"]);
XmlDataSource1.DataBind();
Repeater1.DataBind();
}
The page in which this Page_Load resides is called by a parent page. Each time this Page_Load gets called the value of "file" in the query string will be different. So each time I will be receiving the XML contents from a different file which are inserted into the XmlDataSource and then bound against by the Repeater. Getting the XML data from the file works great but when I bind against the repeater that only works the first time through Page_Load. Each time after that when this code is executed the same results from the first XML file are displayed in the repeater.
What am I missing here. How can I get the XML data to be bound against the repeater on each page load instead of just the first one?
I have web app which stores certain things on a page in a cookie when the page posts back in case the user doesn't finish what they're doing and come back later. But now I must do a javascript time-out and actively save the info to the cookie rather than wait for the user to postback. All my cookie code is on server side where I use Response and Request objects to read and write cookies and I want to leverage that. So I would like to just use ajax calls to a webservice. Is there a way for me to access Request and Response objects and read and write cookies to the browser via those objects during a webservice call? Or should I just go with javascript?
EDIT: Sorry i wanted to specify that I would like to use jquery-ajax.
I have a webservice (ASP.NET) deployed on a webfarm. A client application consumes it on daily basis. The problem is that some of its calls are duplicated (with difference of milliseconds). For example I have a function Foo(string a,string b). The client app calls this webmethod as Foo('test1','test2') once but my log shows that it is being called twice or sometimes 3 or 4 times randomly. Is this anything wrong with the webfarm or the code? Note that the webmethod has simple straighfarward insert and update statements.
View 1 RepliesI got an ashx file to create an image. I am referencing it via web.config like this:

Actually the handler never gets called. I already searched the forums and tried some tips and hints. But nothing of that worked. Try to call the url via[URL]
I made a custom handler that derives from MvcHandler. I have my routes using a custom RouteHandler that returns my new handler for GetHttpHandler(), and I override ProcessRequest() in my custom handler. The call to GetHttpHandler is triggering a breakpoint and my handler's constructor is definitely being called, but BeginProcessRequest() is being called on the base MvcHandler instead of ProcessRequest().
Why are the async methods being called when I haven't done anything to call them? I don't want asynchronous handling, and I certainly didn't do anything explicit to get it. My controllers all derive from Controller, not AsyncController.
I don't have the source code with me right now, but I can add it later if needed. I was hoping someone might know some of the reasons why BeginProcessRequest might be called when it's not wanted.
I have an IHttpHandler that I would like to hook into the OutputCache support so I can offload cached data to the IIS kernel. I know MVC must do this somehow, I found this in OutputCacheAttribute:
public override void OnResultExecuting(ResultExecutingContext filterContext) {
if (filterContext == null) {
throw new ArgumentNullException("filterContext");
}

I am trying to add page with custom extension, say .asp2 with my set of html tags.Now whenever i try to access the page on browser...it asks me "Save as". This happens because I am using an extn which the server is not able to recognise.What should I do to so that my server, IIS 5.1 recognises this extension??
how to associate custom events on such custom page?
I am trying to implement an IHttpHandler. I have defined an appropriate class but the debug web server (you know, the one you get if you hit f5 in Visual Studio) is responding with "Can't Display Page".I looked here http://msdn.microsoft.com/en-us/library/ms228090%28v=VS.90%29.aspx to learn how to configure the handler, and it seems there are different ways for IIS6 and 7. But the process is put something in the web.config and then set it up in IIS Manager. However, that is a deployment issue. I want to be able to run it in the test server, and I don't know how to do this second step in the test server.I put the following in my web.config:
<httpHandlers>
<add verb="*" path="*.sample"
type="MyNamespace.Code.HelloWorldHandler"/>
</httpHandlers>
HelloWorldHandler is the code from the link above (wrapped in MyNamespace.)
Can someone let me know how to configure this correctly for the development server?
I'm working on a reporting script which runs a number of reports (pdf) on button click. The reports are created on the web server then I'd like the user to be given the option to download the files. I have worked out the script for downloading one file from the server. But I'm not sure how to download multiple files? (there will probably be about 50)
After I run one report I redirect the user to a http handler script.
Response.Redirect("Download.ashx?ReportName=" + "WeeklySummary.pdf");
public class Download : IHttpHandler {
public void ProcessRequest(HttpContext context)

I want to create an HTTP handler within my project. To do this, I created a new class, and tried to implement IHttpHandler.
Each time I do this, I get the error 'End of statement expected'.
I know that normally you can create a new class library and create a class to implement a handler. But why is it not possible to do this in an existing web project?
I have an IHttpHandler that implements IRequiresSessionState. Everything works fine on most servers but there are 2 servers (one IIS 7.0 and one IIS 7.5) that give me null sessions. Aspx pages are fine on every server. I've searched for hours and failed to find anything that is not related to IRequiresSessionState.
View 1 RepliesI am trying to create url routing like this[URL] but I am having few questions , first why he is adding lines to the web.config , I tested it and it didnt appear that they're doing something as I commented them and nothing major appeared second I am having this line of code that is crashing var display = BuildManager.CreateInstanceFromVirtualPath(_virtualPath,typeof(Page)) as IProfileHandler;
when casted as ihttphandler it's working , but when I am casting it to iprofilehandler(which is implemeting ihttphandler) it's giving null !
First, I'm looking for a a small example of how to handle a series of RESTful URLs, such as /Account/{userName} and /Account/{userName}/Profile with a single HttpHandler. At this time, I'm not interested in embracing MVC or using the REST Starter Kit. Should I place the HttpHandler class in a Class Library? Should I publish to the root of the RESTful URL?
My second issue stems from the fact that my ASP.NET hosting is done through a web-hosting company. Will I need to ask their tech team to configure IIS for me? Is that normal practice?
I want to implement a restful service in ASP.NET. I want it to be compatible with .Net 2.0 and IIS 5+. I am constrained to not use ASP.NET MVC or REST starter kit. By reading on internet I have learned that it can be implemented using HTTPHandlers. The problem is, the request will come in as a POST request. And I want to URL to be like:
http://abc.com/MyService/MyMethod1/
and
http://abc.com/MyService/MyMethod2/
I created an application and implemented IHTTPHandler for all incoming request ending with ".aspx" extension.Under "ProcessRequest" module, I am creating an instance of HttpContext (with URL attributes different from my application's URL i.e. if I am working on localhost then speciying Yahoo.com as its URL) and assigning it to "context" which comes as method argument.After redirection, an error is generated. Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)Code is as follows.

View 3 RepliesMy page (which basically contains a pair of Repeaters) renders and is displayed to the user.I'd like to have a "Download" button on the page which, when clicked, will propmt the user to save the page locally as an html file without losing any of the CSS formatting.
My CSS files are linked to via a Master Page.Currently, I have the button linked to some javascript that open will the Save As dialog, but all of the CSS formatting is lost, and it saves the page .I'm assuming that the button will need to open a new page which will re-create the data for the Repeaters and then save using StreamWriter, but I'm not exactly sure if that's right or how best to do it.
