Ok, from what I found isValid doesn't look for all protocols specified in the url RFC so I don't really want to rely on that.
My idea: 1. check the string to see if it only contains alpha and numerical characters. This way I know if it's just a string like 'ksdfjk3490' that's not a url. if it was an ip, it would have '.', and the only possibility i could think of was someone using netbios names or local host names like computer1 computer2 etc. but in that case i'd expect http://computer1 If this fails, disqualify the string. remind user to put protocol in string like http://computer1.com 2. If step 1 passes, check the string to make sure that the leading characters are one of the following http:// https:// ftp:// afs:// telnet:// gopher:// nntp: news: mailto: and if one of those is found, pass it as a valid url. there's a lot of possibilities so rather than be restrictive i'm just going to check for a valid protocol. if one is not found, I'm going to assume http:// and add it to the string. I want all of my redirects in the database to have their proper prefix so that there are no redirection issues. However, I tried the following code. I've had a long day, so maybe i'm overlookign something simple. <CFIF refindnocase("http://","#redirect_url#",1) AND refindnocase("https://","#redirect_url#",1) AND refindnocase("ftp://","#redirect_url#",1) AND refindnocase("mailto:","#redirect_url#",1) AND refindnocase("gopher://","#redirect_url#",1) AND refindnocase("nntp:","#redirect_url#",1) AND refindnocase("news:","#redirect_url#",1) AND refindnocase("afs://","#redirect_url#",1) AND refindnocase("telnet://","#redirect_url#",1)> <CFSET redirect_url = "http://"&#redirect_url#> </CFIF> if the string already has http://, it doesn't add anything. if the string doesn't have a prefix, it adds http:// if the string has any of the other prefixes, it adds http:// -- 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 !!
