$15-30 USD / hour

We have several custom apps made in C++ (specifically Codegear / Embarcadero RAD Studio / formerly Borland) and Delphi. (customer/order management ..email client etc) Some of these are server / client apps. In other words, there's a server app that performs connections / writes to/reads from MS SQL databases... as well as hosts the client apps. Then there's the client apps (for multiple users) which connect to the server. Our apps utilize Indy socket library [login to view URL] for TCP/IP communication I believe between Server and client apps and vice versa. They also use Indy for connecting to IMAP/SMTP server to receive/send emails. Occasionally, we'll receive socket errors, such as: Socket Error # 10060 Socket Error # 10054 Connection reset by peer. I'm looking for someone who has actually monitored/ troubleshot / fixed these issues before. If you've fixed these issues before as well as are familiar with Indy components, that would also be a plus. I'm told those errors can be caused by quite a number of possibilities such as bandwidth issue, Firewall/router, Machines rebooting, etc. Another issue we face....our custom C++ apps communicate via https using WinInet and OpenSSL DLL's with our website PHP file. sometimes we get EWinInetException: Error sending HTTP request. WinInet Error (12002) ....but it is intermittent. I do not think our web server is at fault but I could be wrong. Thanks!

Hello. I've lot of fun with Indy components in my projects. Most likely the issues related to TLS/SSL handlers. So I would first check encoding protocols enabled and make sure OpenSSL or other SSL-enabled libraries are up to date. Regards, V.
