[twsocket] ICS SSL support for Delphi4...

[Paul Dirschka]

Hello,

I'm looking at ICS-V5 which seems to fully support Delphi4, but I don't see the 
any SSL (esp.
tSSLHttpCli) support for that version.  I've retrieved both OverbyteICSV5 and 
ICSslSrcV5i which I
believe are all that is required.  The ICSslSrcV5i has packages for Delphi 5 
and later but none for
Delphi 4.  Is there some reason that D4 won't be able to implement ICS SSL?

Thanks,
Paul

[twsocket] ICS SSL support for Delphi4...

[Paul Dirschka]

That was not the answer I'd hoped for but I thank you for it none the less.

I'm thinking that I will create my tsslhttpcli based code in D7 as a DLL and 
link it in my D4 application. Do you think that might
work?

Thanks,
Paul

[twsocket] Proxy question OverbyteICSHttpstst...

[Paul Dirschka]

Hello,

I'm testing OverbyteICSHttpstst GET that is failing when passed through Squid 
Proxy 2.7. 
The request is successful when used without the proxy.
The request is successful using Firefox or IE using the Proxy.

Following is the log generated by the failed request in OverbyteICSHttpstst.  
If you notice something that might help me understand
why this is failing please let me know.

The request seems to be handled by the proxy (at least initially) successfully, 
and then SSL handshake to the site also seems to be
successful, but from what I can tell the GET never makes it to the host. 

Thanks,
Paul
