delphi indy10资料说明书，英文版(Delphi indy10 data sheet, English Edition)

delphi 2010自带的10.5.5版本的Indy在支持OpenSSL方面存在问题，最好是升级到10.5.7(the 10.0.5 version indy has some problem with delphi 2010 in dealing openssl you can update it to 10.5.7 to fix it)

indy 10.6网络连接插件。delphi7自带indy9 不过差一些东西。(indy 10.6 connect to internet)
