Hi Guys, I had some more pressing coding to work on, so I put this on the back burner. I'm revisiting it now. I am working on a url redirect service. The core of it is working, but I want to integrate some better url checking functions. Right now, if someone enters a long url to have shortened, the form will accept anything.
The only thing I am doing is checking to see if the string has 'http://' and if not, adding it to the string. so that something like thisismyurl.net would get saved as http://thisismyurl.net This is obviously flawed, as if someone were to enter ftp://thisismyurl.net it would get saved as http://ftp://thisismyurl.net So here is my idea Check for http://, but also check for https://, ftp://, mailto:, file:, and news urls. Only if there is no match after that, then add http:// to the front of the string. This is because many people may enter in thisismyurl.net, but if it is a url for any of the other protocols, people will have to enter that anyway. So the only url's that won't have a match would be standard http:// ones since only those url's are often written without it. After that check, I am then going to run the string through 'isvalid(url, string)'. If it passes, then I will accept the url. Is that good enough? I'm also going to have it setup so that any .exe, .bat, etc. files don't do an instant redirect. With standard urls, they will redirect automatically. With url's that contain executable files, users who use the shortened url will get a warning page that the url contains an executable file and that they need to click on the link at their own risk. In regards to checking for executables, right now i'm thinking about just parsing the string for .exe, .bat, etc. and if any of that is found anywhere, flag it. What do you guys think? Sound logical? I don't want to be too restrictive and potentially block valid url's, and many people may have valid reasons for redirecting to executables, but i want some order at least. -- Open BlueDragon Public Mailing List http://www.openbluedragon.org/ http://twitter.com/OpenBlueDragon mailing list - http://groups.google.com/group/openbd?hl=en !! save a network - please trim replies before posting !!
