Identifying a homepage

[ChrisRChamberlain]

Hi all

Need to programatically determine a homepage from a URL.

[URL unfurl="true"]http://www.tek-tips.com/threadminder.cfm?pid=215&page=1#postform[/URL]

The third "/" in the string marks the end of the homepage, so

[URL unfurl="true"]http://www.tek-tips.com/[/URL]

is the homepage.

What exceptions are there going to be to this theory, please?

TIA

provided the URI is normalised and you are working from the left, I can't think of one.

So long, and thanks for all the fish.

Thanks for your response.

By way of further information, the URL is derived in only two ways.

[ol]
[li]OLE Drag 'n drop from the browser addressbar onto a form, whereby the dropped data is the string of the displayed URL[/li]


[li]OLE Drag 'n drop from a link or favourite onto a form where the dropped data is *.url, and the file is parsed to extract the string[/li]
[/ol]

To my knowledge, both versions are normalised under all circumstances unless someone can advise to the contrary?

One exception I can think of immediately is when the protocol specified in the URL is file instead of http. For example:

file:///c:/myfile.html

I'm sure that there may also be exceptions for other protocols.

Hope this helps,
Dan

Thanks for that - it's also easy to error trap.

Another exception would be pages where they have a image/animation intro where the homepage is actually

http://www.site.com/home.html

Also hosted sites (ex.

http://www.angelfire.com/scifi/mypage).

You should also remember that if there no third backslash (although some browsers add this if missing), for example:

[URL unfurl="true"]http://www.google.co.uk[/URL]

then you should just take all text after the second backslash.
