Sure. Html can save the data on client side. It is done by cookie.
There is example:
If index1.html have those lines:
<div id="busines_12" pararule="para1">
<div class="para1" name="email_address"></div>
<div class="para1" name="user_name"></div>
It can be used as 12.0 in index2.html as the value of "email_address" in index1.html. 12.1 int index2.html as the value of "user_name" in index1.html.
It is done by the framework of tagcgi. It's object is to make HTML can be used as PHP or C++ to write client or server sides scripts.
