<div>Hello,</div><div>We're trying to provide an iCal feed from Seaside (on VW) to Drupal. The Drupal use of the feed can be tested using a Google calendar iCal feed, and it works fine. We're able to produce a simple iCal document as well, but Drupal does not accept it. Both the Google and our Seaside iCal feeds download fine with just the browser.</div>
<div><br></div><div>The one big difference we can see in the header is that the Google contains 'Content-Encoding: gzip' and ours does not. I have not be able to determine how we can properly provide the gzip compressed version of the content. </div>
<div><br></div><div>Has anyone done an iCal feed from Seaside to Drupal? Or, how can I get the gzip properly to be properly supported in my data source? </div><div><br></div><div>Thanks for any help,</div><div>Bob Nemec</div>
