Step #4
Create a new file, rubydev\ch05\textfields\public\input.html, adding this code:

<html>
<head>
<title>Using Text Fields</title>
</head>
<body>
<h1>Working With Text Fields</h1>
This Ruby on Rails application lets you read data from text fields.
<br>
<form action = "\look\at" >
Please enter your name.
<br>
<input type="text" name="text1">
<br>
<br>
<input type="submit"/>
</form>
</body>
</html>

the code <form action = "\look\at" > is problematic, as the URI scheme, used by html, does not allow for backslashes ("\").

the correct syntax would be <form action = "/look/at" >.

though the former works on internet explorer 6, it does not on firefox.
