Shanti Subramanyam commented on OLIO-90:
----------------------------------------
The same fix has now gone into all 3 drivers. Since the drivers won't be merged
in 0.2, it is essential to keep them synchronized.
> Simulation of browser caches incorrect

> Key: OLIO-90
> URL: https://issues.apache.org/jira/browse/OLIO-90
> Project: Olio
> Issue Type: Bug
> Components: generic
> Affects Versions: 0.1
> Reporter: Shanti Subramanyam
> Assignee: Shanti Subramanyam
> Priority: Minor
> Fix For: 0.2
>
>
> The driver simulates browser caches by not requesting the images included in
> a page 40% of the time. In reality, browsers make an 'if-modified-since'
> request to the server and the server checks if the file was modified later
> than the date specified in the request and if so it will return the file.
> Thus, this will incur an additional request/response cycle which we are not
> capturing in the driver/server interaction.
> This bug will require fixes to both the driver and the server side. The
> driver can use a timestamp equivalent to when the run started. The server
> code (for PHP) must check for the existence of the if-modified-since flag.
> For rails, since the app does not service these files, the server will
> automatically take care of the request.
