Re: "Too many Redirects".

Hello Hugh,

Amaya is based on the libwww for HTTP requests and there is indeed a 
maximum of redirection allowed in the library (I guess to avoid infinite 
loop). By default this maximum is set to 5 and Amaya set it to 7 at the 
initialization (so more than the spec suggests).
I haven't see any difference between HTTP 1.0 and HTTP 1.1 concerning 
this aspect in the library.
So , there is no way in the current version to dynamically change this 
I guess it's the first report on this problem, the mail you pointed out 
concerns a redirection problem for the PUT method and I think it has 
been fixed.
