Dear list,

I’ve troubles for having SSI working with proxy\_pass, when I use FastCGI  
it works fine. I believe I’ve made a mistake but so far it’s a mistery  
for me!

The PHP code proxied looks like this:

\<?php echo '' ; ?\>

and the site configuration like this:

# nginx 0.8.20

upstream apache  
{  
server 127.0.0.1:8080 ;  
}

server  
{  
listen 80 ;  
server\_name localhost ;  
ssi on ;

access\_log /var/log/nginx/localhost.access.log ;

location /  
{  
ssi on ;  
root /home/fb/www ;  
location /ssi  
{  
internal ;  
}  
}

error\_page 404 @php ;  
error\_page 403 @php ; # for the main page eg: “/”

# proxy the PHP scripts to Apache listening on :8080

location @php  
{  
rewrite ^(.\*)$ /index.php?$1 break ;  
proxy\_set\_header X-Real-IP $remote\_addr ;  
proxy\_redirect off ;  
ssi on ;  
proxy\_pass [http://apache](http://apache) ;  
}  
}

The SSI directive is not processed by Nginx when the upstream reply (it  
appears as an html comment).

Does anyone have a clue?

Best regards

Found what’s happening! In Apache mod\_deflate was activated, just set it  
to off and it works fine.
