I am going through the process of removing Wget and Curl dependancies from Jack, the former I have removed completely now.
In order to remove Curl though I need to be able to do two things, the first of which I *think* is impossible with the current
version of the DownloadFile() command.
1) I want to be able to compare the date of a local file against that of a remote file and only if the remote file is newer does
the transfer begin. At present I use Curl with the -z argument in order to do this.
curl -z ENVARC:jack/featured.xml http://www.lakewebdesign.co.uk/jack/featured.xml -o ENVARC:jack/featured.xml -silent
2) Still thinking on this one, I need to be able to call a .PHP script with URL params. Shouldn't be a problem as long as DownloadFile()
is set to Redirect so I can get the resulting content. In fact thinking about it- it should be a non-issue. When Curl does this it appends
HTTP Headers at the front of the content- I suspect I will still have to handle that.
Anyways typing it down here makes it somewhat clearer for me on what I have to do. However, I suspect point (1) will keep Jack reliant
on Curl for the one instance (at present) it is required in the whole app.
