RE: Iconize weather info and something else

[Ray v. B. <r_v...@ho...>]

The problem with the loading part in the first part of the page and the 
reconstruction of the "Loading..." text is that the server does not return a 
page before the entire page is processed, at least that is what i see. Maybe 
with very large pages, the browser does not wait for the end and starts 
displaying before it has received the end.

Martin, you're right. Generating a new page from js which contains php is 
not parsed at the server but processed in the browser directly.
