php - cURL SSL version 2 vs version 3 -

-

i have written php script transfer large files (100mb+) server using curl. process wasn't working until set curlopt_sslversion 3. without setting option, process transfer 7mb, die.

i understand why case before push process out of our customers' machines. server specific? certificate specific? want make sure won't have instances customers need ssl version set 2 work.

if can enlighten me on this, appreciated.
