[Bug 1399246] Re: PDF embeds fail in sites with subdomains for user pages

 

For the record, here's how to replicate this issue, if you're too lazy
to set up wildcard DNS.

1. In your config.php, set "cfg->cleanurls" and
"$cfg->cleanurlusersubdomains" to true.

2. Add a subdomain to your /etc/hosts file for the username "user1". For
example, for a local Mahara site at the domain "mahara.test" I would put
this line in /etc/hosts: "127.0.0.1 mahara.test user1.mahara.test"

3. Do a clean Mahara install.

4. Create a user with username "user1"

5. Log in as user1, create a page, put a PDF block in that page, then
make the page visible to the public.

6. View the page in display mode. It will be shown with a URL like
"user1.mahara.test/pagename"

Expected result: You should see the PDF content displayed in the PDF
block.

Actual result: The PDF block title shows up, but you do not see the PDF
content.

  PDF embeds fail in sites with subdomains for user pages

Bug description:
  The PDF content block fails to render the PDF iframe in a user's View
  if Mahara is set up to have subdomain urls for users, e.g.
  http://mikekelly.mymahara.org/mikes-page

  This is due to the X-Frame SAMEORIGIN rule enforced for Mahara pages.
  The PDF is served from the main domain, while the View page is served
  from the subdomain.

  This does not affect group Views, or the editing interface for Views,
  where the user identifier subdomain part is not used in the url.
