Abstract

The invention provides a method for indicating that a link on a web page is to an external link previously this was done by the webmaster. The current method carries this out by the client software comparing the domain name of the current document'"'"'s URL with that of the link in question, and applying a visual indicator to the link if it is external.

Claims

1. A method of indicating that a link on a web document accessed by a client using web browser software is to an external link, wherein said web document has an associated document object model, the method comprising:

identifying links in said web document by querying said document object model associated with said web document;

comparing a URL domain name of said web document to a URL domain name of an identified link;

providing an indication associated with at least one identified link that said at least one identified link is external when the URL domain name of said web document is different from the URL domain name of said at least one identified link;

for each identified link, comparing a URL sub-domain of said web document to a URL sub-domain of said identified link; and

providing an indication associated with at least one identified link that said at least one identified link is internal but in a different sub-domain when the URL sub-domain of the web document is different from the URL sub-domain of said at least one identified link and the URL domain of the web document is the same as the URL domain of said at least one identified link.

2. The method of claim 1 wherein said indication comprises one or more of the following:

a change in a mouse cursor when the mouse cursor passes over the at least one identified link;

an audible indication when the mouse cursor passes over the at least one identified link;

a tactile indication when the mouse cursor passes over the at least one identified link; and

a vibration when the mouse cursor passes over the at least one identified link.

7. The method of claim 1 wherein identifying links comprises identifying all links in the web document.

3. A computer program product for indicating that a link on a web document accessed by a client using web browser software is to an external link, wherein said web document has an associated document object model, said computer program product comprising:

a computer usable medium having computer readable program code means embodied in said medium for;

identifying links in said web document by querying said document object model associated with said document;

for each identified link, comparing a URL domain of the web document to a URL domain of each identified link;

if a URL domain name of the web document is different from a URL domain of at least one identified link, providing an indication associated with said at least one identified link that the at least one identified link is external;

for each identified link, comparing a URL sub-domain of said web document to a URL sub-domain of said identified link; and

providing an indication associated with at least one identified link that said at least one identified link is internal but in a different sub-domain when the URL sub-domain of the web document is different from the URL sub-domain of said at least one identified link and the URL domain of the web document is the same as the URL domain of said at least one identified link.

4. The computer program product of claim 3 wherein said indication comprises one or more of the following:

a change in a mouse cursor when the mouse cursor passes over the least one identified link;

is an audible indication when the mouse cursor passes over the least one identified link;

a tactile indication when the mouse cursor passes over the least one identified link; and

a vibration when the mouse cursor passes over the least one identified link.

8. The computer program product of claim 3 wherein the code means for identifying links comprises code means for identifying all links in the web document.

5. An article comprising:

a computer readable modulated carrier signal;

means embedded in said signal for indicating that a link on a web document accessed by a client using web browser software is to an external link;

wherein said web document has an associated document object model, said means comprising means for identifying links in said web document by querying said document object model associated with said web document;

for each identified link, comparing a URL domain of the web document to a URL domain of each identified link;

if a URL domain of the web document is different from a URL domain of at least one identified link, providing an indication associated with said at least one identified link that the at least one identified link is external;

for each identified link, comparing a URL sub-domain of said web document to a URL sub-domain of said identified link; and

providing an indication associated with at least one identified link that said at least one identified link is internal but in a different sub-domain when the URL sub-domain of the web document is different from the URL sub-domain of said at least one identified link and the URL domain of the web document is the same as the URL domain of said at least one identified link.

6. The article of claim 5 wherein said indication comprises one or more of the following:

a change in a mouse cursor when the mouse cursor passes over the at least one identified link;

an audible indication when the mouse cursor passes over the at least one identified link;

a tactile indication when the mouse cursor passes over the at least one identified link; and

a vibration when the mouse cursor passes over the at least one identified link.

9. The article of claim 5 wherein the means for identifying links comprises means for identifying all links in the web document.
