Dear all

Trying to move my pages from Apache to nginx (1.2.1 on Debian stable  
with  
backports), I run into the problem of having used SSI’s ‘exec cmd’ for  
more  
than a decade quite intensively.

What is the best and easiest way to emulate ‘exec cmd’ with nginx?

For example, in my footers I make use of dynamically change between  
ENglish  
and GErman with a shell script as easy as

with setlanguage.sh as

echo “\<a href="$(echo $REQUEST\_URI | sed -e  
‘s:/EN/:/GE/:’)"\>Deutsch”

When I try using , the script  
is  
executed. However, instead of just adding the link, nginx includes the  
German web-page fully.

Is there an easy way to get the same functionality with nginx?

Thanks for any hint.

Best regards  
Lukas

In this particular case I would recommend using if with regular  
expression and echo commands instead. Something like this should  
work:

\<a href=“/GE/”\>Deutsch

(Untested.)
