Hyperlink length

L

Lisa B

I'm trying to hyperlink -- however, it is a long URL and it is cutting off in
the Address bar. Is there a limitation on the character length of they URL in
a hyperlink?

Bill Dilworth

I tested this and the maximum total length of a local hyperlink (including
filename and file extension) appears to be 247 characters. This is a
Windows file system limit, and may not be a hyperlinking length limit. I
don't think there is a different set of rules for net links, as I was able
to create an MS-like internet hyperlink of 243 characters that did not fail.

I'm not sure about long links to servers that have long file path/names, but
good heavens people, if you can't link to it in under 100 characters, maybe
it is best left unfound. :) With just a hundred alphanumerics we can
create 2 * 10^162 links, I'd think we could find something both available
and meaningful within that many possible links.

That's really cool. How the heck does it work?
I just used it to create a tinyurl from a Cognos PowerPlay bookmark of over
260 characters. And it works! But how?

I assume they must keep a database of these requests, mapping their short
index to the long URL I input to their site.
- Is this secure?
- Who is paying for this (what is the business model for this service)?
- How long will this tinyurl continue to work?

No database required. If you look at the html code (right-click view source),
you will see the large humongous address on the left, and the generated tiny url
address (what you see on the page) to the right. as long as these two bits of
information stay together, the url will last forever <g>

Michael,

You'll have to explain this because it doesn't make any sense to me. If
you give someone the tinyurl.com address, all they have is the very small
address. Tinyurl.com must maintain a database to match the tiny address
to the real URL. Perhaps, I am misunderstanding your answer.

As far as I know, the addresses will theoretically stay around forever,
but that will only last as long as the Web site. I do not know their
business model because they don't seem to be making any money off my use
of their site (no advertising, no fees, not even any registration for
future solicitations).

As far as privacy, they could be collecting a fairly random assortment of
long URLs, but I can't think of any reason why I should care, but I am
willing to learn why I should care (I do generally care about privacy
issues).

OK. I must be really dense because I still don't get it (as a college
professor, this is a good experience for me because I have to explain
things all the time to people who don't get it, so now the shoe is on the
other foot).

When I copy a tinyurl, I only copy the address. There is no hidden <A
HREF="http://www.loyola.edu/therestofthereallylongaddressthatistoolongtop
ostinanmessageoraddtoanemail.html">. So, I can type
http://tinyurl.com/d4hld into my browser, and it will take me to the full
address, I believe, after rerouting me from tinyurl.com.

Please explain to me what I am missing. Thanks.

I think there is, if you look at it in an html editor, or turn on Rich Text in
your newsreader. Go to the Tiny Url page, view the source code, and look at the
example they have there.

Nope. There isn't. I can simply type the URL into a browser, rather than
clicking on a link, and it will work. I think there has to be a database
at tinyurl.com that links this. Otherwise, a non-html email wouldn't
work, typing into a browser wouldn't work, a plain text newsreader
wouldn't work, etc.

Test it out. Go to your browser and type:

t i n y u r l . c o m / d 4 h l d

It will work (if, of course, you leave out the extra space I inserted so
you can't cheat).

David;

I owe you an apology. Your correct, I took it apart, and it is as you said.
Could have swore that I saw the other code. Better get my glasses checked

When you copy a tinyurl created address, your copying two parts. The
part you see in the document, Davids Stuff here and the actual hidden
original long address that points to Davids Stuff.

Tiny url just generates the part that you see. The Davids Stuff above
came from editing this address http://tinyurl.com/d4hld

That is how I think it works.

Darn. I was rooting for you at least in the hope that I could get some

things that I'll easily find another example.

No, if TinyURL.com vanishes, all TinyURLs vanish along with them. In
other words, don't put your epitaph on your tombstone in the form of a
TinyURL address, but for short-term use, it is great.

Dude, you NEED to make it to PPTLive. It's thoughtfully sited in a hotel whose
back door leads to a shopping center that sports a decent bookstore and a
Chinese/Japanese restaurant that does a decent line in sushi.

And Steve can order in Japanese for you!
