Hello everyone!

A cache issue…

I created an XML file order.xml with this simle cotent:

\<?xml version="1.0" encoding="utf-8"?\> John D. Foo Str. 3, 10117 Berlin 

and saved it on my VM in /var/www/sandbox/test/. As you can see, it’s  
not a  
valid XML (s. tag address). So the browser (XML parser) threw an error.

Then I repaired the file. But the browser is still throwing the same  
eoor.

It’s defently the server(-side) cache, since I’ve already tried it out  
in  
several browsers.

How can/should I set up the cache behavior of nginx?

It’s probably browser caching - Did you try pressing Ctrl+F5 or clearing  
your browser’s cache?

As I’ve already said: It can only be the server(-side) caching. Since  
revoming of the browser cache and Ctrl+F5 don’t help.

But now I think, it might be an issue of the virtual machine. Because  
when I  
edit the files directly from the VM\* and not in my hosst system,  
sometimes I  
can see the changes in the Browser.

- The files are saved in a shared folder, so I can access to them both  
–  
from the host and also from the guest system.

When using virtualbox shared folders, you need to turn off sendfile in  
nginx.

That is an old well-known bug in VitualBox. See:

Hello!

I have to reopen this topic, because the issue is back…

I have a basic host file, that defines thr root folder for a host as:

# file ax-common-vhost

server {  
if ($host ~ ^(?.+).(?.+).loc$) {  
set $folder “$area/$project”;  
}  
…  
root /var/www/$folder/;  
}

Now I want to add another basic vhost file for Zend Framework projects.  
There the webroot should be in the older “public” directly under the  
root.  
So I created a copy of my basic vhost file with a new root rule:

# ax-zf-vhost

server {  
if ($host ~ ^(?.+).(?.+).loc$) {  
set $folder “$area/$project”;  
}  
…  
root /var/www/$folder/public/;  
}

# file zf1sandbox.sandbox.loc

include /etc/nginx/sites-available/ax-zf-vhost;

But it’s not working. The server tries to open the path of the  
zf1sandbox  
project root, cannot find any index file there and throws a 403 error.

I’ve already set the sendfile setting to “off” in all relevant  
files/segments:

# file nginx.conf

http {  
…  
sendfile off;  
…  
}

# file ax-zf-vhost

server {  
location / {  
index index.html index.php;  
sendfile off;  
}  
}

Sorry, my mistake. It’s another problem. The server is not analyzing my  
zf1sandbox.sandbox.loc file, that includes the template for Zend  
Framework  
vhosts (include /etc/nginx/sites-available/ax-zf-vhost;), but is using  
my  
common template (ax-common-vhost).
