=head1 DESCRIPTION |
50
|
|
|
|
|
|
|
|
51
|
|
|
|
|
|
|
This is a lightweight middleware that adds the C |
52
|
|
|
|
|
|
|
header required by GoogleEChromeEFrame to take over page rendering, |
53
|
|
|
|
|
|
|
for requests made from a browser with ChromeEFrame installed. |

This is a much more aggressive middleware. Visitors running |
68
|
|
|
|
|
|
|
InternetEExplorer without ChromeEFrame installed are prevented from |
69
|
|
|
|
|
|
|
seeing the site at all: they only receive a page instructing them on how to |
70
|
|
|
|
|
|
|
install ChromeEFrame. |
