Verifiy Hyperlinks

Hi. Question. Is there a way to check if a hyperlink address still
exists? That is, if you're online. Got a database with a hyperlink
field. Just want to flag dead links. Any advice is
appreciated...Dennis

the only way to verify an email address is to send to it.

The only way to verify an http address is to attempt to retrieve it. Of
course there are sites that go down for maintenance, network issues, DNS
issues ....

Try to connect. If you can't, it may be bad, or it may just be temporarily
down.

Using WinSock, open a TCP connection to port 80 of those IPs (kind of
like using telnet to port 80). Then issue a GET and see if you got a
textual reply.

Haven't run this code but it should be pretty close to what you want.
local oHTTP, cServer
cServer = "www.microsoft.com"
xmlhttp = create("Microsoft.XMLHTTP")
xmlhttp.Open("GET", cServer, .f. )
xmlhttp.send()
* Check the contents of xmlhttp.responseText to see whether you got 'page
not found'

Interesting code, Paul.
I was triyng it but it's givin' me an OLE unspecified error 0x80004005 at
the open() line.
I'll google after it in the spare bits of time, looks like 0x80004005 is
found in many different kinds of context, from ODBC to who knows what...
