Sorry for my english

I noticed that with XOOPS if i change an url adding at the end &some_word, the link works anyway
for example
scrivere questo indirizzo:
writing:
http://www.beverfood.com/v2/modules/wordbook/entry.php?entryID=293
It's the same of
http://www.beverfood.com/v2/modules/wordbook/entry.php?entryID=293&ACQUA%20MINIMAMENTE%20MINERALIZZATA
or using semplified url
http://www.beverfood.com/v2/wordbook+entry.entryID+293.htm
It's the same of
http://www.beverfood.com/v2/wordbook+entry.entryID+293+ACQUA+MINIMAMENTE+MINERALIZZATA.htm
So i changed some templates of some modules adding at the link of an entry &<{$link.title}> for have the title in url too
here some examples:
hack of xdirectory based on the module mylinks:
I have chenged link.html templates
from:
<a href="<{$xoops_url}>/modules/adirectory/singlelink.php?cid=<{$link.cid}>&lid=<{$link.id}>"/><{$link.title}></a>
to:
<a href="<{$xoops_url}>/modules/adirectory/singlelink.php?cid=<{$link.cid}>&lid=<{$link.id}>&<{$link.title}>"/><{$link.title}></a>
I've just added &<{$link.title}> at the end of the link url:
you can see it here:
http://www.beverfood.com/v2/adirectory+viewcat.cid+177.htm
click over any link
example:
http://www.beverfood.com/v2/modules/adirectory/singlelink.php?cid=177&lid=13565&COBIT%20ITALIA
The same thing here:
http://www.beverfood.com/v2/wordbook+category.categoryID+5.htm
wordbook module (example
http://www.beverfood.com/v2/modules/wordbook/entry.php?entryID=170&ACIDO%20CITRICO )
templates wb_category.html
from:
<a href="<{$xoops_url}>/modules/<{$eachentry.dir}>/entry.php?entryID=<{$eachentry.id}> "><{$eachentry.term}></a>
to:
<a href="<{$xoops_url}>/modules/<{$eachentry.dir}>/entry.php?entryID=<{$eachentry.id}>&<{$eachentry.term}>"><{$eachentry.term}></a>
I've just added &<{$eachentry.term}> (Term title) at the end of the entry's link
Now i have the title in the url but i'm using simplified url hack and it doesn't work:
for example i want to chenge:
http://www.beverfood.com/v2/modules/wordbook/entry.php?entryID=170&ACIDO%20CITRICO
to
http://www.beverfood.com/v2/wordbook+entry.entryID+170+ACIDO+CITRICO.htm
I'm not a php programmer so......
Are there any chances to change simplified_url.php for have + intead of %20?
Sorry for my english
