Stratergies to stop CDN always hitting Heroku
Hi If I have a blog url structure, something like www.blog.com/12343/Hello-World I'm happy to cache that page entirely at the CDN But concerned that my low-dynamo app might be easily exposed to attackers by simply making many calls to blog posts that don't exist that always make a Heroku request because the CDN wont have them cached. It would be easy to rapidly request a sequence of fake blog post urls that hit my little dynamos and also database. What are the strategies to deal with this?? Can the CDN impose rules? Can Heroku help in any way? cheers -- -- You received this message because you are subscribed to the Google Groups "Heroku" group.

Cloudfront
Hi there My site has a lot of static pages, and I'm hoping I can use Cloudfront to host them and stop requests hitting Heroku. (Yes I know there are other possibilities like memcached and varnish) Does anyone know of a good guide in setting this up? It's not very clear to me. thanks -- You received this message because you are subscribed to the Google Groups "Heroku" group. To post to this group, send email to heroku@googlegroups.com.

does varnish care about query strings?
Hi have to URLs which are identical except for a differing query string I was expecting them to be cached differently but they are not :( Is this because varnish ignores query strings? . or do I have a bug in my app? thanks :) -- You received this message because you are subscribed to the Google Groups "Heroku" group.

Re: Mobile strategy
Some Content Delivery Networks offer device detection and ESI based on this.

Re: Mobile strategy
Yes, I was about to say all these techniques (other than the css media queries) require a hit to the backend. Ideally there would be detection on the edge/cloud, so varnish cache can kick in where possible without hitting a rails stack or sinatra. Still, good ideas in this thread. -- You received this message because you are subscribed to the Google Groups "Heroku" group. To post to this group, send email to heroku@googlegroups.com.

Re: Mobile strategy
You are doing this in the backend? Some people are checking the user agent in the front end... but that seems too late (if u can help it) What are your differences in what is delivered? Do you have different markup and content for mobile? If so I guess caching your URIs might be difficult if each URI needs to have different versions for mobile and desktop. unless you could somehow map or redirect to m.xxx.com and treat it entirely separately. thanks for any tips -- You received this message because you are subscribed to the Google Groups "Heroku" group.

Mobile strategy
Hi there Is anyone using Heroku to serve a mobile and desktop version of their site? How to handle device detection? Particularly when using the some URLs to deliver different markup/content to the two different platforms. Any ideas of a device detection strategy? Even if it was just "mobile" or "desktop" (as opposed to detecting specific handsets). cheers -- You received this message because you are subscribed to the Google Groups "Heroku" group.

Re: Action Caching... force it to use Varnish not Memcache

Action Caching... force it to use Varnish not Memcache
Hi everyone Is there a way to force Action Caching to cache to Varnish and not use Memcache? Yes I fully realise this might cause (?) the next request to hit Varnish and not my app, which defeats the purpose of Action Caching and I should use Page Caching... but I have my reasons :) If there was a hack or a tweak, or any ideas, I'd be super happy! thanks -- You received this message because you are subscribed to the Google Groups "Heroku" group.

Hey The price difference for 100mb Redis or Memcache is only $5 I may have it wrong, but thought Redis provides very similar functionality, with extra useful functionality Why or when would someone chose Memcache over Redis?

HTML5 manifest caching on Heroku
Adam Wiggins kindly put up a cache manifest example: http://cachemanifest.heroku.com/clock.html I notice that this does work when I reload the page that is already open in iPhone Safari However if I load the clock url on a fresh safari page, the cache does not kick in. Is this a heroku issue? The manifests seem to be set up ok from what I can see? The reason I am wondering is that other manifest examples, outside of heroku, do work eg: http://www.thecssninja.com/demo/offline_webapp/ -- You received this message because you are subscribed to the Google Groups "Heroku" group.

Re: DDOS attack alleviation?
Just as an aside Does Varnishing as much content as you can protect you from DDOS? It would cover your app backend but is Varnished content on Heroku so heavily cached that it is impenitrable? I assume it must be, since a Reddit attack is as bad as DDOS, and Vanish is what people recommend for Redditing? I guess I'm asking this because I'm thinking one option is to make your site still accessible in a cached format when necessary if your backend/database overheats ... some sort of graceful fail -- You received this message because you are subscribed to the Google Groups "Heroku" group.

Image upload -> manipulation -> copy to S3
Hi First of all, I realise Heroku encourages us to upload directly to S3. However I'd like to manage that upload via Heroku first. Two questions: 1) With Heroku I understand your request can have some temporary space for file uploads. Can I rely on that space to exist for a few minutes while a Delayed Job gets to it? 2) Does uploading a file completely lock a dyno? Or can a single dyno handle a few simultaneous uploads? cheers -- You received this message because you are subscribed to the Google Groups "Heroku" group.

using MongoHQ while keeping Postgres for some things... possible?

bestbuyideax.com - ran on 8 dynamos?
Saw this on heroku's twitter: "http://bestbuyideax.com is now blazing along on 8 dynos at @heroku." Really? Seems to me that site has the same level of dynamic content as a quiet discussion forum.
