Hi there.
I try to describe the problem as better as I can.
I'm developping some mini-apps that can be viewed by many (most of them) mobile devices. Since I uploaded the first proyect this week I begun writing a RAR Online-Uncompressor, as a friend's request. I guess this mini-app will be useful for many people. I done it, and tested within my localhost. But when I tryed it once in my host, something gone wrong, and now it throws an http 500 error. It uploads the *.rar file, but not uncompress it.
At the other hand, could I get access to some statistics? Only for getting information about what kind of devices access to my apps.
Thanks.
Edit:
I fixed that, but now I have another question. Do I have permission to execute commands? Like
echo `rar e ...`;
