I'm have a camping/resort/rv website that uses PHP's native SoapClient
class to request availability for units within a resort. The end users
fill out a form indicating the type of unit they would like, dates, number
of adults, etc things like that, and then we use that data in the SOAP
request. Most of the time, it works as expected.
There have been reports where a user is checking availability on a unit but the data returned indicates none are available. Then, if they switch to a new browser, and do the same search over, it's showing that they ARE in fact available.
This is perplexing, because we aren't doing any caching of the returned data, as it's (obviously) required to be up to date at all times.
I suspect that the SOAP server is set up with persistance, but I can't tell. My client's IT guy isn't very forthcoming with the data. He says that he's been able to reproduce the bug (I haven't).
Finally, we're looking at ways to debug this. I have no access to the data behind the SOAP server, so I can't tell what availability is supposed to be. The only thing I can think of to do is log all the availability requests and then review them the next time the error occurs.
Any thoughts?
