[Laszlo-dev] Snippets make 2 requests when font tag is present

[Antun Karlovac]

cacheWrapper seems to be Webtop-specific. I grepped both the OL and the 
Webtop source trees. It's a folder where Webtop keeps embed code, the 
wrapping HTML page, etc.

But the weird thing is that the SWF makes two separate HTTP requests for 
the compiled import. Is it at all possible that Webtop somehow overrides 
OpenLaszlo import behavior?

Here's what the webtop-lzmail/calendar/cacheWrapper directory looks like:

$ find cacheWrapper
cacheWrapper
cacheWrapper/browserdownload.html
cacheWrapper/download.html
cacheWrapper/footer.html
cacheWrapper/images
cacheWrapper/images/background.png
cacheWrapper/images/cancel.png
cacheWrapper/images/download.png
cacheWrapper/images/footer_bg.png
cacheWrapper/images/powered_laszlo.gif
cacheWrapper/images/powered_laszlo_mo.gif
cacheWrapper/images/template.png
cacheWrapper/images/warning.png
cacheWrapper/lps
cacheWrapper/lps/includes
cacheWrapper/lps/includes/embed-compressed.js
cacheWrapper/lps/includes/embed.js
cacheWrapper/lps/includes/excanvas.js
cacheWrapper/lps/includes/script.js
cacheWrapper/lps/includes/utils.js
cacheWrapper/lps/includes/vbembed.js
cacheWrapper/mail.js
cacheWrapper/mainframe.html
cacheWrapper/style.css
cacheWrapper/util.js
cacheWrapper/webtop.js
