Re: working around status code 429

Hi Ray,

sorry for the delay. I updated the output file in the file curlrun1 to
point to tmp, which is a path that exists. I attached a 7zip file
"files.7z" of the input file "curlrun1" and the output file "out".  I
used the following curl command:

curl --retry 30 -v -w "%{http_code} %{url} %{filename_effective}\n"
--compressed -K ./curlrun1 --parallel -L > out 2>&1

When I do

cat out | grep "429 h"

I get the output:

429 /tmp/626.2.html
and more.

So to my understanding the are 429 errors, which are not retried,
although I used --retry in the call to curl.

Yours Dirk
