Re: [google-appengine] Re: Static files in newly deployed version not available in the apps domain. (Major problem)
Caching is a best effort attempt to reduce load and should never be thought of as a foolproof mechanism to prevent requests from hitting your server. In the case you are describing, URL parameters still work since they prevent the proxies and browsers from storing things they shouldn't store. Most proxies and browsers key off URL, including any request parameters. I have personally never seen browsers or proxies that will not cache a URL with parameters, but I believe they may exist. It's not the worst thing in the world if your assets are not cached - in some cases it is 100x worse to serve a stale asset, especially if your app is JavaScript heavy. In any case, URL rewriting is a pretty good technique as well, I just don't think it's fair to call appending a query parameter problematic, as I feel it is is an overall easier approach than URL rewriting. In either case, they both encourage the best practice of creating methods in templating language to rewrite image, media and JS tags. For instance, in JSPs, you could have something like the following to output tags: %= AssetTag.imageUrl(someImage.jpg) % (I should write a blog post or something about this subject.)

Re: [google-appengine] Re: Static files in newly deployed version not available in the apps domain. (Major problem)
Ah, interesting argument. I've never personally been in a situation where we've had to replace CSS referenced images enough times that manually changing their URIs was a problem, even in environments where I was deploying 5+ times a day. In practice, every time I've used CSS referenced images, they've been because of backgrounds (rare changes), rounded corner hacks or other browser hacks that don't change enough. I think you may have sold me, and at the very least I shouldn't knock it until I try it. Anything to kill those nasty cache issues that pop up. Moral of the story: always use a cache buster.

Unless you want to change your CSS files manually every time you replace an image or do it in a build using some script, you cannot version an image that you use from CSS. On the other hand, if you name the CSS file: http://example.com/static/123456/css/base.css and make the URLs relative in CSS: background:url(../group/google-appengine/icon?hl=en); Then the browser will call the URL: http://example.com/static/123456/ group/google-appengine/icon?hl=en Every time you change a version number, it affects ALL your static files in one shot, with zero work for you. Including images from CSS, and many other things that can be done relative. I agree that caching is not something that works accurately and predictably, but you can still make it more effective by avoiding known problems. If you are into rapid development, where you release almost every day, then the advantage of zero work system for versioning static files is invaluable.

Re: [google-appengine] Re: Static files in newly deployed version not available in the apps domain. (Major problem)
The tradeoff with request parameters is that you need to output your image and asset tags in your HTML templates to append a parameter and be version aware. The benefit, however, is that it is an almost 100% foolproof way to bust caches. You don't only have the Google edge cache to worry about - you've always got to worry about ISP proxies, browser caches + other caching schemes that users introduce between their computers and your application. I highly recommend doing this, as you will spend countless hours debugging user issues (I have) that are cache related that could be easily solved by appending a URL parameter. This is especially true if you use any kind of JavaScript code that changes. What are the other problems? On Tue, Jun 15, 2010 at 1:13 PM, TL twl.e...@gmail.com wrote: That is really the only solid way to do it. Using request parameter has too many problems to list. I did this in a Java app and it does require you to write some code, since as you mention Java does not have a built in rewrite capability. I may add google code project with a Java implementation for app engine (using the app engine version as a directory). Will keep you posted. E On Jun 3, 12:35 pm, Donovan donovan.jime...@gmail.com wrote: Another technique for cache busting is URL rewriting within the path to the resources, which has some benefits over the query string usage in certain cases. The Python AE runtime supports URL mapping for static resources which can make this even less painful and allows long expire times - so for example you could generate all static URLs like this: /static/[app version from environment]/css/foo.css and have it map to the static/your/foo.css withint your appengine upload This has an advantage in the case of css because then all your resources referenced from the CSS (as long as they're using relative URLs under the same static directory) are also affected by the path versionion. So a background-image: url(../images/bar.jpeg) ; declaration in the foo.css above would cause the browser to request the resource with the injected app version /static/[app version]/ images/bar.jpeg. This would not happen with the query string cache busting technique unless you willing to parse your css dynamically (and then you're not using the static file appengine servers). Using this technique you can feel free to set your static file caching headers to large values (months to a year) to get a better client experience without sacrificing the ability to update your app at will (your app version id will change everytime you upload, which creates a new URL and new set of cacheable objects to the browser) Unfortunately, the Java AE runtime does not have a similar support for static file URL rewriting - I've done a feature request here (PLEASE STAR! :) )http://code.google.com/p/googleappengine/issues/detail?id=2070 So, to get the same behavior and peformance benefit of hitting the AE static file servers, you'd have to physically create a versioned directory during the build process before uploading to appengine . You could do the same thing for the python as well, but the URL mapping feature is so easy to use I've never wanted to do so. - Donovan -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Re: Static files in newly deployed version not available in the apps domain. (Major problem)
Hey guys, I've tracked this down, and it is working as intended. Our infrastructure may or may not respect your cache headers and just cache assets for your application. It's clear that's what's happening here, with some front-ends caching and some not caching. The worst case scenario is that cache headers are not respected; the best case scenario is that all requests are served from an edge cache. Most developers will fall somewhere in between. If a cache header is set, you should not assume that the edge cache will expire it. On the flip side - you should also not assume that a deploy will invalid the cache, as the edge cache has no knowledge of your code being updated. In general, use of a cache-buster for static assets is an absolute must in web development for all the reasons I mentioned in a previous post: ISP, reverse proxy caching, desktop accelerators, weird browser caching, etc. I'll make it a point to make the documentation about our edge caching infrastructure more clear about this and include examples on how to correctly include media, stylesheets and Javascript includes.

Re: [google-appengine] Re: Static files in newly deployed version not available in the apps domain. (Major problem)
I can't reproduce this. Here's my YAML file: application: ikailan-com version: 1 runtime: python api_version: 1 default_expiration: 1d handlers: - url: / script: main.py - url: /assets static_dir: assets Can you guys post your app.yaml?

Unfortunately, there's no way to invalidate items in the frontend cache, so you'll have to use a cache buster or wait for the TTL to expire.

Can you guys confirm? Also - are you guys setting any headers? Which headers get returned? I've personally always used cache busters for the simple reason that sometimes users using web-accelerators or with aggressive ISP or caching settings tend to key off the URL. Can you guys use this workaround in the meantime?
