Sorry, I described the error without checking my code - my app has
something like " if curl_status <> 0 then http_error_code=500 ", so that
curl failures are reported to the user like any other http error.
libcurl just says " curl_status<>0 : of course.

Well, I just do this anyway, in the app. (Actually, LWP does the same,
making up its own 500 errors on most failures). Its handy for me, as I'm
just passing the error text back to a user, but if I was doing a
non-user based app, I'd prefer the real status mechanism...

A nice idea - I guess the 'error' function could fake up a whole 500
reply depending on the switch, though its tricky to call all the correct
file and callback hooks after that. In fact, it might be easier to have
it as a curl feature, rather than a library feature - it seemed easy
enough to do this for myself in my app, and get the specific format that
I wanted.

I did, and it did. I just added a line before my other check: " if
curl_status != 0 and http_error_code=302 then curl_status = 0 " :-)

Well, of course, I'm solved now, but perhaps its a curl feature rather
than a libcurl feature?
