chttp Error

[Stressed_Simon]

I use a 3rd party company to handle my Credit Card transactions called Protx. I
build the interface last year and it has been working fine since July last
year. This morning the chttp call that initiates the transaction is producing
the following error.

Connection Failure: Status code unavailable

Now I can navigate to the page manually and it is there and I cannot for the
life of me work out what the problem is.

So any help would be great.

Have you checked with the 3rd party credit card processing company and asked what changed at their end?

I spoke to them on the phone and they said that they had been under a
DDoS attack since yesterday and they said that they had moved there IP
as their whole range was under attack. They ensured me that payments
were going through and that I need to flush my DNS.

I tried pointing straight at their new IP instead of the domain name
and it still isn't helping.

If I navigate tot the page in the browser it is there so I don't think
it is a DDoS???

Apparently ColdFusion caches DNS data and that is the problem as they have moved and we can't see it.

Does anyone know how to flush ColdFusion DNS cache?

Got this from Tom Jordahl's blog. Finally got it sorted.
