I am using Salesforce communities built on Napili theme. I have 2 different community pages and both has 2 different lightning components (i.e. the 2 components are not same hierarchy). I want to pass variables (collection type List) from 1 component to another. Can we do it? 

Note : I have disregarded passing varaiable values in URLs and fetching them since I want to send a List Collection type.

Hi.. I am using <iframe> tag in my VF page and want to post doubts:

1) I am using src as bucket url - "https://bucketeer-8c4ead3e-9208-43cb-bb6c-f4a5cc3b597e.s3.amazonaws.com/......html/". I have set the X-Frame-Options to "Allow" for my bucket. Now when I use the above path as src, instead of showing the content of .html file it is directly getting downloaded and when I see the console, I find below:

"Resource interpreted as Document but transferred with MIME type application/octet-stream in iframe"

2) Since I was not able to get any positive solution on 1, I was trying to implement "http://jsfiddle.net/Y9beh/", however same doesnt work in my Salesforce instance. 

Can anybody please comment on above mentioned points?
