Given a HTTP URL I need to get the redirect URL, i. e. what you get from a 30x HTTP error code.

I don't want to download something, just get hold of the "real" URL that a browser would be redirected to.

How could I get this?

If you just look at the HTTP header, you can get the information you want. For instance, try "curl --head www.war.com", and note the "Location: " field in the reply.

Does this resolve 302 errors?

I ask because hdid doesn't seem to be able to handle redirects. At least for

hdid http://www.schubert-it.com/download/vektor3.dmg -verbose

for example it returns something like "failed - http code 302". Or is this not the cause why hdid can not mount this image?

curl --head http://www.schubert-it.com/download/vektor3.dmg

doesn't show any location field.

If you're not trying to automate it, you can do it manually. Open a terminal window and type what's in red below (note TWO return characters after the HOST: line):

% telnet www.schubert-it.com 80

However, as you can see, this gives a 200 (OK), not a 302 redirect. If it were a 302, you should see the redirect in the headers. If not, replace the 'HEAD' command with a 'GET' to return the entire page (although it's not a good idea to download a binary file in the manner in a terminal )

Automating it was the idea. If it's not moved, then why does hdid give me that error? Here's what it says:

hdid http://www.schubert-it.com/download/vektor3.dmg -verbose
hdid: DILoadDriver: checking for disk image driver

What does that mean?

Is there anybody who knows this?

Probably www.schubert-it.com is on virtual hosting. I posted an explanation of what causes the problem in this thread:

Alternatively, instead of telnetting to port 80, you can use curl -I, e.g.,

curl -I http://somehost.com/somefile

Sure it is. Thanks for the explanation.

Unfortunately there doesn't seem to be a way to get the "real directory" of the file then.
