<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> </head> <body> <% success = 0 ' This example requires the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code. set http = Server.CreateObject("Chilkat.Http") ' The FollowRedirects property controls whether redirects ' are automatically followed. The default behavior is to ' automatically follow redirects. ' Explicitly set FollowRedirects so that redirects are NOT automatically taken: http.FollowRedirects = 0 set resp = Server.CreateObject("Chilkat.HttpResponse") success = http.HttpNoBody("GET","http://yandex.ru/",resp) If (success = 0) Then Response.Write "<pre>" & Server.HTMLEncode( http.LastErrorText) & "</pre>" Response.End End If status = resp.StatusCode Response.Write "<pre>" & Server.HTMLEncode( "HTTP Response Status: " & status) & "</pre>" ' The FinalRedirectUrl property will contain the redirect URL ' If FollowRedirects was equal to 1, then all of the ' intermediate redirects (if any) would be followed until ' there were no more redirects. However, because ' FollowRedirects is not 1, FinalRedirectUrl contains ' the next redirect URL. loopCount = 0 Do While (status = 302) Response.Write "<pre>" & Server.HTMLEncode( "Redirect URL: " & http.FinalRedirectUrl) & "</pre>" nextUrl = http.FinalRedirectUrl success = http.HttpNoBody("GET",nextUrl,resp) If (success = 0) Then Response.Write "<pre>" & Server.HTMLEncode( http.LastErrorText) & "</pre>" Response.End End If status = resp.StatusCode Response.Write "<pre>" & Server.HTMLEncode( "HTTP Response Status: " & status) & "</pre>" ' For safety, prevent infinite loops by ' keeping a loopCount and only allows following a max ' of 10 redirects: loopCount = loopCount + 1 If (loopCount > 10) Then Response.Write "<pre>" & Server.HTMLEncode( "Too many redirects.") & "</pre>" Response.End End If Loop %> </body> </html> |
