Hi,

I want to get some data about books on various websites : ISBNdb, GoogleBooks, Worldcat... This works well with all of them, but not always with Amazon.fr : with it, using the same URL, I do not get always the same content! Sometimes, it is the one I get with Firefox, and sometimes it is another. This seems to be aleatory, and any content I get, there is never any error (HttpRequest::GetError() returns 0).

Trying with wget (I am using Linux), I see that with this URL, there is 3 redirections. Could it be the problem ? And if not, what could it be ?

My code is very simple : I'm supposed to know the URL for the book (if not, I make a search on the ISBN of the book, and I always find the right URL, even on Amazon.fr - if the book is known on the site, of course !)

String content;
HttpRequest http;
...
http.Url(url);
content = http.Execute();

An url showing this problem :

http://www.amazon.fr/14-Jean-Echenoz/dp/2707322571/ref=sr_1_1/278-1397759-3160153?ie=UTF8&amp;qid=1372075436&amp;sr=8-1&amp;keywords=9782707322579

Any idea ?
