Document Expired?

[doubledee]

When I hit the back button in my browser I get this...

Document Expired

       

This document is no longer available.

       

The requested document is not available in Firefox's cache.As a security precaution, Firefox does not automatically re-request sensitive documents.Click Try Again to re-request the document from the website.

 

What is causing that?!

this is a problem in the Beta versions of firefox with the Cache. you could add

Cache-Control: max-age=600

 

 

this sets it so the cache doesn't expire for at least 10 minutes.

I'm running FF 10.0.2  That isn't a "Beta"?!

 

 

you could add

Cache-Control: max-age=600

 

this sets it so the cache doesn't expire for at least 10 minutes.

 

Are there any downsides to that (e.g. security)??

shared cache can be a Security risk Yes. that is why firefox by default has it's security settings to expire after a certain amount of time. this can also be done server side as well in PHP.

 

what kind of documents is the code getting IE images/files 

 

 

if your getting a file or image inside a folder make sure the user has permission to 777 or 755. chmod wise.

here is a cache class that sets the file permissions and allows you to start and stop the cache delimiter.
