问题 How can I completely supress the output of the Cache-Control Header that is returned by my custom HttpHandler in ASP.NET? I know, I can change the header field by modifying response.Cache and response.Cache.SetCacheability, but that will only change the header field, not remove it. That is not what I want. I completely want to make no assumptions about the Cache-Control field and leave it up to the browsers policy. EDIT: The same holds true for HttpResponse.Charset. If no charset is set, ASP

问题 I generate an XML/Google sitemap on the fly using an Http Handler, so that I don't need to maintain an XML file manually. I have mapped my Http Handler to "sitemap.xml" in my web.config like this: <httpHandlers> <add verb="*" path="sitemap.xml" type="My.Name.Space, MyAssembly" /> </httpHandlers> It works nicely. Now, www.mywebsite.com/sitemap.xml sets my Http Handler into action and does exactly what I want. However, this url will do the same: www.mywebsite.com/some/folder/sitemap.xml and I

问题 I have a MS SQL view that I want to make available as a CSV download in my ASPNET Web Forms app. I am using Entity Framework for other views and tables in the project. What's the best way to enable this download? I could add a LinkButton whose click handler iterates over the view, writes its CSV form to the disk, and then serves that file. However, I'd prefer not to write to the disk if it can be avoided, and that involves iteration code that may be avoided with some other solution. 回答1: You

问题 Here's what I want to do: 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.

Queries: Is it possible (it should be given the hype about integrated pipeline etc. in IIS 7)? How to do it? 回答1: Here's

问题 I have statiс files in website folder, but need to check permissions for every file. I decided to use HttpModule for that purposes.
