browser check
29 October 2005, 06:10
maybe a mod for the forum / whole page
i use it on my whole site
features:
check the client browser
check the client version
check the client os
check if the browser can pass the site
first of all big thanks to marcelg for the spider and mobile code (included here)
--> demo screen
make a file called --> <font color="red">browser_check.asp</font id="red">
to pass a browser set:
browser_pass = 0
to
<font color="red">browser_pass = 1</font id="red">
you can make version number checks too
(see above for internet explorer)
the variable -->
<font color="navy">browser_OScheck =
browser_Ncheck =
browser_Vcheck = </font id="navy">
can set to -->
"ok" "false" "warn"
(used to display icons on the error page,
if you don't want you can delete it)
