Openflashchart Error 2032 with SSL and Internet Explorer #869

I'm experiencing this issue (http://dwairi.wordpress.com/2009/01/15/open-flash-chart-ie-and-ssl) with piwik 0.4.1.
As indicated in the article, this only surfaces if SSL and IE are used.
Firefox, Safari and Opera are fine.

I attached a picture of the incident.

The URL seen in the picture is:

index.php?module=VisitsSummary&action=getEvolutionGraph&columns[]=nb_visits&idSite=1&period=day&date=2009-06-15,2009-07-14&viewDataTable=generateDataChartEvolution

As suggested in the blog article above, the following statements inserted in apache's config will fix this.

BrowserMatch MSIE HAVE_MSIE
Header set Expires       "Thu, 01 Jan 1970 01:00:00 GMT"        env=HAVE_MSIE
Header set Cache-Control "must-revalidate, cache, public"       env=HAVE_MSIE
Header set Pragma        "public"                               env=HAVE_MSIE

I couldn't pinpoint the culprit file, so I tried applying this to all (which works).

This shouldn't make a difference, but I have mod_rewrite rules in place to ensure SSL is used.

RewriteEngine On
RewriteRule   /piwik\.php|js)    -                        [L]
RewriteRule   (.*)               https://%{SERVER_NAME}$1 [R,L]

I can't reproduce this regression of #550 on my dev environment.

What version of php are you using?
Without your Apache config changes, what do the headers from your Piwik installation look like?

Replying to vipsoft:

PHP Version 5.1.6

See the attached file - this is a trace of all requests and responses after clicking the login button.

Thanks.

It looks like our header changes aren't being applied in the data-file stream. (Lines 1038-1046 and 1060-1068.)

(In [1306]) refs #869 - fix Flash+IE over HTTPS

fuero: please test the patch.

Tested with IE 7 and IE 8 on Windows XP, works as expected.

Thanks.

(In [1702]) Only send the 'https work in IE please' headers when in https mode, so that graphs are cached in non-ssl (better user experience when viewing multiSites dashboard) refs #869

THis appears to be a regression for reverse proxies where the backend server is http, and only the proxy is https.

(In [fixes #869 - Installation - detect presence of a reverse proxy and warn if mismatch with $_SERVER'HTTPS'); add 'reverse_proxy' config setting
