Parse error with Generic Handler using IIS

由 会有一股神秘感。 提交于 2019-12-13 12:18:53
问题 What made me curious is that the generic handler works just fine when I'm running the Web App in a Visual Studio ASP.NET Development Server. When I change the config to run it directly from IIS the handler just dies. It's an image handler, it writes back an array of bytes to be rendered in an Image object. As I said, it works fine in VS Development Server, but fails on IIS. It doesn't even get called... The error I get when I'm trying to call it directly is this: Parser Error Description: An

Using a colon (:) in a url with ASP.NET/IIS

由 青春壹個敷衍的年華 提交于 2019-12-13 05:44:25
问题 I'm implementing a custom controller in ASP.NET MVC and really want to be able to use a colon in the urls, so that I can identify class/column names and their values, like so: http://example.com/user:chaiguy ...but apparently ASP.NET or IIS doesn't allow colons in urls. I did some digging and apparently it's considered a security issue, but , I'm using MVC and am handling all url paths manually (just treating them as strings), and not relating them to the file system, so I'm pretty sure this

asp.net HTTPHandler prevents page from loading

由 佐手、 提交于 2019-12-13 05:29:48
问题 I have an ASP:NET web project with a simple HTTPHandler which filters out requests from outside IPs. The code itself works, but the HTTPHandler prevents my page from loading . No error. No infinite load. There's just a blank page. If I remove the reference in the config, it loads perfectly fine. It's definitely caused by the HTTPHandler. I've also stepped through the handler and the code is definitely reached, it's just that when the handler is done, the page doesn't load like it should. Here

Streaming PDF via invocation of HTTPHandler using $.get into object element

由 北慕城南 提交于 2019-12-13 05:23:25
问题 What I am trying to do is invoke an HTTPHandler via the $.get method of jQuery which will stream back a PDF and display it in a web page using an object element. My previous method of setting the src attribute of an IFrame to be the result of a handler invocation works, but I would like cross-browser completion notification, so have moved to using $.get(). Sample code: function buttonClick() { $.get("/PDFHandler.ashx", {}, function(data, textStatus, XMLHttpRequest) { var pdfObjectString = "

How can I programmatically modify an aspx file content before the handler handle it?

由 无人久伴 提交于 2019-12-13 03:56:24
问题 The reason I need to modify the content of an aspx (not physically, but change the content in the memory) is because there are certain custom tags I made needs to be parsed to the correct data before the entire aspx is handled by the HttpHandler. Is there a way for that? 回答1: You can use Response Filters (HttpFilter) and modify content on the fly, basically after response is formed, before EndRequest your filter is called (it's a stream descendant) and you can modify it as you wish. In the

Viewstate in a .ashx Handler?

由 萝らか妹 提交于 2019-12-12 11:37:25
问题 I've got a handler (list.ashx for example) that has a method that retrieves a large dataset, then grabs only the records that will be shown on any given "page" of data. We are allowing the users to do sorting on these results. So, on any given page run, I will be retrieving a dataset that I just got a few seconds/minutes ago, but reordering them, or showing the next page of data, etc. My point is that my dataset really hasn't changed. Normally, the dataset would be stuck into the viewstate of
