.NET Forum / ASP.NET / General / February 2008ASP/ASP.NET page that reacts a special way to items coming from a particular subdomain (programmatically testing subdomain?)
Please help me think through this one. 1) I have DNS and IIS set up on my server. 2) I've written ASP and ASP.NET webpages that behave in certain ways when a variable is set via querystring or in code. They render as "mobile-optimized" pages when they receive the right params via QS. 3) I've configured subdomains on my server, e.g: mobile.mydomain.org 4) What I want is for requests that come in on mobile.mydomain.org to render themselves as mobile pages. My choices: 1) Best: Can I test programmatically in classic ASP/ASP.NET whether the requests are coming from my mobile.mydomain.org? Could you tell me how? 2) Alternate: What would be the smartest way to do this in IIS -- maybe by configuring a new website and inspecting host headers? Any liabilities for existing sites? Any other tactics? Thanks for any guidance you can offer. -KF Hi KF, Regarding on this issue, seems the first thing you need to do is get the servername in url and parse it(to see whether it contains subdomain info). In classic or ASP.NET , there are different means to do this. The following two articles have mentioned some means such as using ServerVariables(available in both ASP and ASP.NET) or the Request.Url property(for ASP.NET): http://www.velocityreviews.com/forums/t98901-point-a-subdomain-to-a-subdirec tory.html http://www.velocityreviews.com/forums/t102142-subdomain-redirect-within-appl ication.html Also, as you said that you may want to display different kind of page depend on this info, I think for ASP.NET, you may consider developing a HttpModule which intercept the request(check the servername in path) and redirect the url: #INFO: ASP.NET HTTP Modules and HTTP Handlers Overview http://support.microsoft.com/kb/307985 http://www.c-sharpcorner.com/UploadFile/hemantkathuria/ASPNetHttpModules1126 2005004251AM/ASPNetHttpModules.aspx http://www.devx.com/dotnet/Article/6962/0/page/4 Sincerely, Steven Cheng Microsoft MSDN Online Support Lead ================================================== Get notification to my posts through email?
