Web1 Get Sequencing

MIT App Inventor Help

I am using a sequence of web transactions to update a server data file.
When I submit eg 4 transactions in a row: T1, T2, T3, T4; they don’t get processed in the same order.
For some reason later transactions arrive at the HOST earlier than the previous ones.

I am curious about the origin of this sequencing issue. Because if I submit the transactions with eg 200ms delay in between each, then they get processed in the correct order.

Does anyone know if this problem is due to the way WEB GET works, or some other reason like caching, or routing, or queuing of transactions etc.

Thanks, TG

you might want to send the second transaction after the first was received successfully and the third after the second was received successfully, etc,
see an example here how to do this https://puravidaapps.com/filebyfile.php
