Let's say I want to download something with wget but the website that has the files I need redirects to a site which automatically chooses a mirror for me (and there's no static file URL provided).
Downloading from such sites works with Firefox, but how do I get real url (not only the link to the redirect page) so I could download these files with wget?
When you've started the transfer in Firefox, cancel it, and right click the download and hit "Copy download link". If you're using an older version, right click it and click on "Properties", and the link will be in the window which opens.
In Chrome - run download as normal - then go to Menu - Downloads - and you should see the direct link which was used. Or press Ctrl + J to open the window.
You can use the LiveHTTPHeaders extension to determine the actual URL of the file being downloaded. (Keep an eye on the GETs in particular.)
This is the answer you have been looking for!
There is only one fool-proof one-click solution: cliget
It gives you a curl command with headers, cookies and all, with a copy to clipboard button, right on the download dialog.
For Firefox: https://addons.mozilla.org/en-US/firefox/addon/cliget
For Google Chrome: https://chrome.google.com/webstore/detail/curlwget/dgcfkhmmpcmkikfmonjcalnjcmjcjjdn/related
While I like wget too, I use another similar tool: cURL. cURL specifically has a feature to follow redirects (-L / --location), and it's also free like wget. I suggest keeping both in your toolbelt; they have some complementary features.
Here's an interesting article I came across on how to use either wget or cURL to download from a site that uses cookies for authentication. There's a mention of the cURL --location feature to follow redirects. (In fact, based on no special flag mentioned for wget, it would seem to me that wget may follow redirects implicitly..?)
In those situations, First I starts the actual download and pause it and copy the URL.
I usually use the firefox DownThemAll addon when there are a lot of links to download and I need to select specific URLs.
It shows the full URL and allows you to add in paused mode so you can start the download when you like.
As an additional feature, you can grab the URL and skip the download altogether.
However, if you need to download the file, DownThemAll is quite good as an accelerator.
Can't you use wget directly using the --trust-server-name flag ? It will download and save using the filename it redirects to.
You can use Curl to download a redirected URL:
curl --location http://domainName/fileName 2> /dev/null > fileName
Your question is a bit unclear. There are 2 urls here : the one you use, and the one that came back after redirection. The first you should know, since it originated from your machine, while the second is the one that displayed in your browser. If the question pertains to where the file is on the redirected server, then there's no way to know.
If you're trying to debug the calls issued towards the server, you can use the firefox add-on of firebug, older versions of it exist here : https://addons.mozilla.org/en-US/firefox/addons/versions/1843.
You can use IDM (Internet Download Manager) when you click on the not direct download link it will redirect the link and showing up the direct link.
Have you tried to pass the redirect URL to wget? Sometimes they work for me.
Here a example from SourceForge:

The version I use:
$ wget --version
GNU Wget 1.10.2
There was an addon for Firefox called Splitlink. It doesn't work for Firefox 3+, but it did work in Firefox 2. If you can find it anywhere (it's not on the official addons page anymore), it will give you more information about the real URL.
If you want a download manager to handle the download instead of firefox, you could use the Flashgot firefox addon.
The firefox copy url is definitely simplest. wget (as the question was tagged) is also a nice solution because you can see all the intermediate bounces, not just the final url:

You could use the netcat tool (which is often included with linux distributions) on port 80 of the website. This shows the full raw HTTP response, including the headers which contain the redirect destination URL. This is one of the most direct ways to get the redirect location, since you are doing the same thing as downloaders do when they follow redirects. Here is an example for the URL http://www.example.com/example.
printf 'GET /example HTTP/1.1\r\nHost: www.example.com\r\n\r\n' | netcat www.example.com 80

Alternatively, many browsers show the actual download URL in the Downloads section. In these, you can start the download and cancel it right away, then copy the URL (from the download history).
