Re: can't login with curl in forum

Wooo many thanks Daniel.
Is too much difficult for me. If you have reason, many security measures to
enter in a simple forum

I've modified timestamp and the html response gives me a :
"An error has occurred"
About hash, x-signature and others I copied headers from curl of the
chrome web development.
I've made some developments with other forums and there is more simply than
these.

Thanks!
