Re: CF DNS Cache
not meant to take over this thread but i am guessing that cf does cache DNS since i get aggregated by adobe feeds and ever since i moved my hosting I have to manually ping it inorder for it to update. if i switch back to my old host then it works fine. - Original Message From: Brad Wood [EMAIL PROTECTED] To: CF-Talk cf-talk@houseoffusion.com Sent: Tuesday, July 8, 2008 5:01:27 PM Subject: RE: CF DNS Cache Hmm, looks like I was wrong.

RE: CF DNS Cache
I don't think that would make a difference. You could ping an aggregator all day long, but if they are caching the IP address your domain USED to point to, it still wouldn't pick up your current feed. The only way I can think of that would work is if you were manually pinging them with a URL that used your IP address instead of a hostname like http://123.123.123.123/rss.cfm. Perhaps your RSS is located in a different place now and you haven't updated your ping URLs in your blog software. Or alternatively, the aggregator uses a separate server to do their automated aggregating, and the server that responds to pings is a different one. i.e. The regularly scheduled aggregating still has your old IP cached, but the ping URL hits an entirely different server which doesn't have it cached. ~Brad -Original Message- From: Sherif Abdou [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 09, 2008 2:41 PM To: CF-Talk Subject: Re: CF DNS Cache not meant to take over this thread but i am guessing that cf does cache DNS since i get aggregated by adobe feeds and ever since i moved my hosting I have to manually ping it inorder for it to update. if i switch back to my old host then it works fine. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;203748912;27390454;j Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:308826 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4

Re: CF DNS Cache
It has to be done via restart, by default. It's actually the JVM that does this caching, and it's configurable via a properties file. I can't remember which one off the top of my head. cheers, barneyb On Tue, Jul 8, 2008 at 2:51 PM, Jenny Gavin-Wear [EMAIL PROTECTED] wrote: Does CF (7) ever clear it's DNS cache, or does it have to be done via a restart, please?

Jason, I haven't done anything with it yet, but the beta version of SimpleDNS has some limited HTTP functionality added.

RE: CF DNS
I can see why this idea would arise, an idle mind? a stalled mind?? an over-revving mind :)) DNS == database; CF uses databases, but using a traditional DNS model, I can't think of any compelling reasons why someone would attempt to do this, beyond idle curiosity. ah, sweet reason. :)) There are, on the other hand, a number of negative technical, security, and performance issues that immediately come to mind. etc, etc. DNS is one hairy piece(s) of functionality. Even if you wrote an CF-achievable, dumbed-down DNS, what's the point vs BIND and all the existing proprietary versions? What is interesting grist for the CF mill is that BIND9 is being delivered with database API using PostgreSQL as the example backend. So I expect CF apps for DNS database admin to appear for BIND9. ( (BIND9 isn't quite ready for infrastructure prime time.) But CF as database web admin app has nothing to do with CF app functioning as a domain name service/daemon. Is CF now used for writing Win32 services and *nix daemons separate from CF templates and an HTTP services?

Re: CF DNS
- Original Message - From: "Jon Hall" [EMAIL PROTECTED] Sent: Thursday, March 22, 2001 9:06 PM It's not really that hard to figure out the sturcture of the dns record files. Just open one up and the write a program that will write the same file with the right names in the right places. We wrote a program that writes the dns files for Microsoft DNS server... The structure of a DNS zone file and records contained therein are as basic as it gets - just lines of text. But I am mindful of Howies achievements with the inFusion mailserver (iMS) - the combination of a custom built services referencing CF templates and/or databases is mighty powerful and flexible. I can give a good example - there are many, many domain registrars and agents out there who give you administrative control over DNS, but not technical control - that is to say - they don't have any way of allowing you to add even simple DNS records such as MX records, A records, CNames etc... It is a big problem - some hosting companies charge $25 to add or modify a DNS record manually to an existing domain hosted by them. It would be great to have a totally CF based domain registration and management system, which allowed users to register a domain with a credit card, and to subsequently login and manage it online themselves - BIG potential right there. I am sure there are lots of other things that can be done up to and including a fully ICANN approved domain registration system. You could even keep zones and records as columns and rows in SQL server - great for administration, management, backups etc.. Providing the custom DNS service talks to UDP/TCP port 53 at the front end, it can get the backend zone data from anywhere. Adrian Cooper. ~~ Structure your ColdFusion code with Fusebox.

Editing by hand or CF writing out a 1000 or 10,000 or 100K line named.conf text is pretty dumb. It's clearly a database pb, so that's why BIND9 has a database API and can read the zone data right out of the database.
