MS Office and IE7 - Githubissues

jbuckner commented 10 years ago

This is a bit of a bizarre issue brought up by Jen in CS:

If a user puts a link to SiteBuilder in an Excel document (it could happen in other Office apps, but haven't verified), we send them to the "Browser Unsupported" page even if it is opening in Chrome or Firefox. I was doing a bit of digging and for some reason, the initial request to SiteBuilder after the user has clicked the link, identifies itself as IE7, even though the website is being opened in Chrome or Firefox.

It looks like there's some discovery happening at first. Look at the end of the user agent. It has ms-office in it.

Here's the Apache logs from a click from Excel:

This is interesting.

The favicon.ico file is also 404ing according to those logs, but it is definitely there.

Ah, sitebuilder, I thought I was looking at yolacom logs.
