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 req

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 r

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

Re: Mobile strategy

Some Content Delivery Networks offer device detection and ESI based on this. This is the ideal solution, but too far outside of the Heroku sandbox - maybe? -- You received this message because you are subscribed to the Google Groups "Heroku" group. To post to this group, send email to heroku@go

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 re

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 ea

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"

Ah thanks for that Not clear it is suitable for image manipulation... as that kind of task is quite beefy, requiring memory, grunt and awkward libraries like imagemagick -- You received this message because you are subscribed to the Google Groups "Heroku" group. To post to this group, send emai

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

Thanks for the reply Chris Can I just confirm that Varnish persists regardless of user page refreshing. The documentation says: "Pressing shift-reload in the browser will cue the browser and Varnish to regenerate the page, regardless of the cache state." http://devcenter.heroku.com/articles/http-

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

Can Redis2Go replace memcahe?

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? Redis is promoted as a way to store sessions, so I assume it is blazin

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?

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 f

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

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. (a few topics a day, a few replies a day, a few "i like this" actions). Correct me if I'm wrong.
