The first problem that can be encountered is that the website will interpret part or all of the code instead of displaying it. A basic example would be to display the html code needed to make text linkable on a website. These codes are interpreted by most forms automatically if the user just pastes the code into the form. The second problem that can arise is that the website will not validate because of the way it has been pasted into the form. Displaying the & char will for example return an error when validating the code. This can lead to all kinds of troubles including broken RSS feeds (read: The XML Feed Cannot Be Displayed).

Displaying valid markup code in websites, forums, blogs and any other page is not difficulty. The only thing that needs to be done to achieve this is to convert all entities before pasting the code. This can be done manually or by using a script like that offered at Spacefem.

All that needs to be done is to paste the code into the form and click on the Make Code button at the bottom. To display the following code on a website

<a href="http://www.ghacks.net/">Ghacks</a>

one would have to paste the following code into the form on the website where the code should be displayed

&lt;a href=&quot;http://www.ghacks.net/&quot;&gt;Ghacks&lt;/a&gt;

html entities converter

This is actually the easiest way to ensure that the website will not interpret the code and that the code will be valid markup code.

An ingenious CSS hack and some spicy Javascript is however enough to use a trial and error method to find out if a user has been to specific websites.

Some webmasters use this method to display the social bookmarking and news batches of websites that their visitors have been through which is very effective in gaining popularity on those websites.

Others came up with a script that is using this method to estimate if the visitor is male or female. The Javascript makes use of the Quantcast Top 10K websites and the male:female ratio that they provide plus a neat algorithm to compute the percentages for male and female likeliness.

Mine turned out 50/50 because I don’t use the history at all. Good luck and let me know what the script thinks about your gender..

The same principle could possible be used to display targeted advertisements. Have been to a lot of parenting websites lately? How about parenting ads? Like sports? How about an ESPN subscription? It’s a bit scary, don’t you think?
