URL handling

[John Allijn]

Hi,
I'm working on a windows application that relies a lot on database qeuries. Both reading and writing of data. 
On the server side I use php scripts. 
In my application I use syntax like "Put URL tURL into tResult".
It all works well, but I am the only user on the database. 
I am wondering what happens when lots of people (about a thousand) use this app. Will livecode wait until the php script is finished? Should there be some error handling on time-outs? If so, what is the best way to do that?
Best regards,
John Allijn
