Is there a way to obtain the last page visited? I don't want to go to
that page, I just want to be able find out what page they came from,
the url of that page. Is this possible?

No. And thankfully so. You can try document.referr er but it won't
always tell you what page they came from.

Why do you want to know where I came from?

Sure, if it is from the same domain, you can use serverside code.

No, if it is from an other site and not referred,
the page has no right to know securitywize.

Found this:
(http://www.samspublishing.com/librar...urs&seqNum=100)

////// COPY & PASTE :

The history object is another child (property) of the window object. This
object holds information about the URLs that have been visited before and
after the current one, and it includes methods to go to previous or next
locations.

The history object has one property you can access:

* history.length keeps track of the length of the history list—in other
words, the number of different locations that the user has visited.

Note

The history object has current, previous, and next properties that
store URLs of documents in the history list. However, for security reasons,
these objects are not normally accessible in today's browsers.

The history object has three methods you can use to move through the history
list:

* history.go() opens a URL from the history list. To use this method,
specify a positive or negative number in parentheses. For example,
history.go(-2) is equivalent to pressing the Back button twice.
* history.back()l oads the previous URL in the history list—equivale nt to
pressing the Back button.
* history.forward ()loads the next URL in the history list, if available.
This is equivalent to pressing the Forward button.

//// END PASTE

Forget you found it.
////// COPY & PASTE :

But it does not tell you where you are in that list.
The history object has one property you can access:

* history.length keeps track of the length of the history list—in other
words, the number of different locations that the user has visited.
But it will not tell you if the page has previous or next entries. Only
how many are in that list.
Note

Pay close attention to the above as it says exactly what I said.
The history object has three methods you can use to move through the history
list:

* history.go() opens a URL from the history list. To use this method,
specify a positive or negative number in parentheses. For example,
history.go(-2) is equivalent to pressing the Back button twice.
Only if there are 2 pages to go back to. And you have no way of
detecting that using script.
* history.back()l oads the previous URL in the history list—equivalent to
pressing the Back button.
Only if there is a page to go back to.
* history.forward ()loads the next URL in the history list, if available.
This is equivalent to pressing the Forward button.

Finally, it says they work "if available". Again, forget you found that
site and find a better one.

Drop your bloody attitude,
I know exactly what has
been said on this thread
and have read my own posting
in detail.

I posted this for informational
purposes, what the f*cking hell
is it with all this fighting and
delusional sense of mastery of
subject.

I was not countering your statements,
merely adding what in what I considered
to be an objective manner.

Bugger off Randy

Me? Attitude? Welcome to Usenet.

It has nothing to do with "mastery" of anything. It has to do with what
this group is about - discussion. If you don't want your
thoughts/contributions discussed then you need to find a new medium to
post your thoughts.

As for "informatio nal" purposes, if it is informationally incorrect
(which that article is) then it is open to be rebuffed, which it was.
I was not countering your statements,
merely adding what in what I considered
to be an objective manner.
And it turns out that your reference was next to useless, incorrect, and
had nothing of value in it.
Bugger off Randy

Now, you bugger off.

Did you read my first reply to your post with the URL? The one where you
copy/pasted from the site and I replied to it, nearly line by line,
telling what was wrong with it and how it didn't help the OP? There is a
lot wrong with the information on that site.

1) If user came to the current page by clicking a link on the previous
page (not choosing a bookmark or typing in the address bar!)

2) If the previus and the current page are in the same security
protocol (http / http or https / https)

3) If a particular server re-transmits REFERRER header (most do but
there are exceptions).

4) If a particular browser doesn't lock reading document.referr er
property (I don't know of any though)

if ((typeof document.referr er == 'string')
&&(document.ref errer != "")
&&(document.ref errer != document.locati on.href)) {
// I am lucky!
var prevURL = document.referr er;
}
