I have asked this question on stack overflow and got pointed towards this forum. My question is below:
Is it possible for a server to simulate a http 408 error? A payment processor is trying to send a http post to my website and they say that in their logs a connection is being made but my server is responding with a http 408 after 0.1 seconds. Is it possible for them to send a 408 back instantly hence no actual timeout?
1 answer i got was:
Certainly a server can return a HTTP 408 error immediately, if it chooses to do so. This would be an abuse of the error code, but it is possible. You may want to use a packet sniffer to see if a 408 is being sent from your server, or from some upstream proxy.
My new question is:
How would i go about checking to see if this is the case?
