I'm not sure if this is the right place for this kind of question so sorry in advance.
I am creating an offline web app for the iPhone, and right now I am renting servers (well, on a free package) for my personal website, so this is where I'm going to store the offline web app.
Anyway, how do I change the .htaccess file in the file manager so that I can add the line 'AddType text/cache-manifest .manifest', I can see the file using the GUI for the file manager but when I try to edit it or change permissions to edit nothing happens - so I guess they've blocked my access to it. What's more is the fact that the file has a size of '0 bytes' and when i try to open it, it is, low and behold 'empty'.
So how do I add this line to the .htaccess so I can finally create this offline web app?
