[Bug-wget] Files downloaded from pages using "303 See Other" named wrongly

[Nicolas Rodsevich]

Hi, I was downloading all files from a site using the following command:

wget  -nd -v -r --accept-regex '.*mod.*resource/.*' --header 'Host: 
catedras.info.unlp.edu.ar' --header 'User-Agent: Mozilla/5.0 (X11; Ubuntu; 
Linux x86_64; rv:23.0) Gecko/20100101 Firefox/23.0' --header 'Accept: 
text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' --header 
'Accept-Language: es-ar,es;q=0.7,en-us;q=0.3' --header 'DNT: 1' --header 
'Content-Type: application/x-www-form-urlencoded' --header 'Cookie: 
__utma=135945449.1331125489.1377905747.1378736807.1378776921.6; 
__utmz=135945449.1377905747.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); 
__utmc=135945449; MoodleSession=bp13b0uafi72eu68v29hlrvih5; 
MOODLEID1_=%25D1%25E3%257E%25AE%250C%257D%2519%25A1' 
https://catedras.info.unlp.edu.ar/course/view.php?id=597

Wget downloaded correctly all files, but when a page used the 303 See Other 
directive to send the file, the file wasn't saved with the name of the mirrored 
page, but with the previous one. Don't know if this is a bug, if it's not it 
would be a good proposal to add an option like --save-with-redirect-name or 
something in order to avoid this bad functionality.

Here is the output of a wrongly named file:

As shown before, the desirabled name would be tp02-topologias-practica-RIP.zip 
rather than view.php?id=10729


Here is the output of a well named file, download without 303 redirect:
