| I detect a fair amount of brain power on these forums so maybe someone can help me. Let's say I provide a way for members to submit a link to another site. The question: how can i automatically validate that the URL is good and a not a 404? If good. accept for later approval, if bad, tell the submitter. |

Use XMLHttp to try to load the entered URL... it "knows" if the request is good or bad ------------- Contribute to the working anarchy we fondly call the Internet |

| thanks for the tip but i'm really looking for a more portable, browser independent solution. could be wrong, but i believe xmlhttp is an activex object for IE 5+. |

The XMLHttp object can be used server side in ASP. You can use it to grab data from another file and then parse it yourself in ASP. Or in your case use it to see if the URL is good, if nothing is returned then the page doen't exsist and the object will through up an exception error. I use it on this site to get meta tags on the search engine submission page at:- http://www.webwiz.net/web_design/search_engine_submission/submission_service.asp - http://www.webwiz.net/web_design/search_engine_submiss ion/submission_service.asp It browser indpendent as the XMLHttp object is running on the server. ------------- https://www.webwiz.net/web-wiz-forums/forum-hosting.htm" rel="nofollow - Web Wiz Forums Hosting https://www.webwiz.net/web-hosting/windows-web-hosting.htm" rel="nofollow - ASP.NET Web Hosting |

it's ugly, it's rude, it's crude. the send method on a 404 has given me a headache but i got it and a 200 working. 200's are your friend. thanks again for your help. time for my nap.
