I haven't been able to find any information on re-use of Salesforce session IDs. It appears that for every invocation of a PHP script that uses the Salesforce API it needs to re-log in. All code I see is written that way. It seems if there was a proxy that stayed resident and maintained the session ID and that each API request went through the proxy the requests would be much faster. Or does Salesforce sidestep the login if the request comes from an IP address that has previously logged in within some time period? I have an associate who codes in .NET who created his own proxy to re-use session IDs and his responses are very fast -- but haven't seen anyone speak about something like that for PHP. Does such a thing exist?

Sorry for the delay. I have not used the session, but I have seen some examples, let me see if I can find the link to the place I found it. I hope it is what you are looking for
