thanks for reply from the lsd.
i checked the 2nd pro. processing time. hmm. about 2-3 sec . so the total time is over 2 sec.
BTW, i red the forum.  i found the strange or important stuff. ie  HTTP connection can be done.. 
but i tried that. but like other user as kasmax, 301 moved to 
http://HTTPS://www.....  so the output is "Renvoyez <strong>tous</strong> les  résultats à  l'aide du formulaire."   i append the content type, content length host etc..  previously i successed by the HTTPS.. so is that really possibily to use HTTP connection rather than HTTPS??
thanks
regards.
