Etags and last-modified over https SSL?

£可爱£侵袭症+ 提交于 2019-12-03 06:36:44
Is it possible to use HTTP caching for conditional GET requests over a secure HTTPS connection? I've got caching working over non-secure HTTP, but when I switch to HTTPS the browser stops sending if-none-match and if-modified-since headers, so the caching breaks. I've tried various Cache-Control settings like public, max-age=3600 and whatnot, no dice. This happens in both Safari and Chrome, so I'm assuming the SSL is breaking it somehow. Is caching not allowed over SSL? And just to be clear, the server is indeed properly setting the etag and last-modified headers, but the browser is not

Is it fine if first response is private with AppCache (Symfony2)?

How to use CXF, JAX-RS and HTTP Caching

问题 The CXF documentation mentions caching as Advanced HTTP: CXF JAXRS provides support for a number of advanced HTTP features by handling If-Match, If-Modified-Since and ETags headers. JAXRS Request context object can be used to check the preconditions. Vary, CacheControl, Cookies and Set-Cookies are also supported. I'm really interested in using (or at least exploring) these features. However, while "provides support" sounds really interesting, it isn't particularly helpful in implementing such

HTTP: Combining expiration and validation caching

不打扰是莪最后的温柔 提交于 2019-12-02 20:35:50
I'm having trouble formulating HTTP cache headers for the following situation. Our server has large data that changes perhaps a couple times a week. I want browsers to cache this data. Additionally, I want to minimize latency from conditional gets as the network is unreliable. The end behavior I'm after is this: Client requests a resource it hasn't seen before. Server responds with resource along with ETag and max-age (24 hours). Until 24 hours has passed, client will use cached resource. After the expiration date, client will perform a validate request ( If-None-Match: [etag] ) If resource
