255047 cache javascript

Hello, I don't know if this is possible, but I will give it a try. I have a website where the frontpage is cached. Every hour the data will be refreshed by a cronjob. Due to ad new features I asked someone to also put weblinks on the frontpage. So it is a .php file with a query that selects 3 records from the database and return the values. A part of the script looks like: $x = list_of_categories_for_item('l',0,$a[c],'<br />',0); $a = array_merge((array)$a,(array)$x); $a[site_url] = $s[site_url]; $pocet++; $aa["url$pocet"] = $a[url]; $aa["title$pocet"] = $a[title]; $aa["category$pocet"] = $a[categories_names]; $aa["image$pocet"] = $a[image_1]; $aa["n$pocet"] = $a[n]; get_detail_page_url('l',$a[n],$a[rewrite_url],$a[category],1); } $b = stripslashes(parse_part('[login to view URL]',$aa)); $lines = explode("\n",$b); foreach ($lines as $k=>$v) { $v = unreplace_once_html(trim($v)); $v = ereg_replace('"','\\"',$v); $complete .= "[login to view URL](\"$v\");\n"; } echo $complete; This file is included with javascriptcode: <script language="javascript" type="text/javascript" src="[login to view URL]"></script> What do I want? I want the data to cache to a textfile, and that i can include the textfile on the frontpage. So it does not everytime load the data. Or does this not make sense and is it not a good idea tio cache this data or does it not effect speed on frontpage?
