using AWS Cloud Front as caching layer

[Katafalkas]

Any1 tried doing it ?

Yeah, booted up a server and a cloudfront distribution real quick to confirm:

You need to turn on the flag that indicates query parameters should be passed to your server. If you don't mind, just let me know when you've taken a look so I can shut it down.

If you don't want to pass query parameters because you're concerned about caching performance, you can modify your web server to rewrite the urls to the query parameters that pilbox needs. For example,

/resize/crop/100x100/http%3A%2F%2Fexample.org%2Ffoo.jpg 

would be translated to

?op=resize&mode=crop&w=100&h=100&url=http%3A%2F%2Fexample.org%2Ffoo.jpg

Or whatever url format you think is appropriate.

Just shutdown cloudfront and the ec2 instance I was using to test, so the links above will no longer work. But, yeah, you should have no problem using cloudfront.

Hey,

Cheers for reply. Sorry it took me so long to get back toy you. I am trying to do the same, but cant get it working. I get the:

ERROR

The request could not be satisfied.


Generated by cloudfront (CloudFront)

error.

As you mentioned above I have enabled the Forward Query Strings option.

I assume you have some kind of webserver in front of pilbox. Are you seeing the cloudfront requests in your access logs?

[Katafalkas]

Hey,

Yeah. I see no requests to NGINX and no tcp packets either using tcpdump dst port 80

[agschwender]

I suspect then that it's more a problem with how configured cloudfront to talk to your server or your server being unable to receive request, and less an issue with pilbox. That is, you should be seeing things in your access log regardless of the backend that you're using to serve your requests.

ok. figured it out. it was to do with infrastructure internals .. cheers for support !
