Don't think it is a good idea to retry it for all errors. Do you know if the 500 error is produced by some specific server software?

Btw. for 6.2 we added a check for 403 already.

You're right, but at the moment we have not better idea. ;-)

As an example, try this Link http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2009:140:0063:0087:de:PDF. Here is a curl output, which shows the 500 error on a HEAD-request. With a GET the document is retrieved.

curl -vI http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2009:140:0063:0087:de:PDF

Hm, ok.
Maybe the server does not like the user-agent.

Can you prepare a patch?

No, I tried some "standard" agents with curl with the same result.

Ok, I'll give it a try. ;-)
