Java is not JavaScript.

Browsers contain a JavaScript parser and executes the code.

HTT contains a rudimentary text parser only. 

Even with extended parsing enabled, how can HTT read the page two link
"javascript: __doPostBack( 'ctl00$Con... tPlaceHolder1$gvresults', 'Page$2')"
analyze it to get the next url and modify that to point to the next url's disk
filename? 

Can't be done. A mirror is NOT a copy. It is a collection of files.
