Https rewrite issue

[apedicdev]

Hello, we have currently a magento store hosted on an nginx web server with page speed enabled. We're having a issue with rewrites as it seems with page speed enabled the rewrite will cause a protocol chain like https -> http -> https. We contacted the host support and they believe is a page speed bug because, when disabled, the issue doesn't occur.

Here is it a redirect test where you can see the double rewrite

Requesting with pagespeed off shows the redirect originally is specified relative:

oschaaf$ curl -I  https://www.vashi.com/round-cut-0-95-carat-halo-engagement-ring-with-side-stones-in-platinum.html?PageSpeed=off
HTTP/1.1 301 Moved Permanently

This looks very similar to what #1055 fixed for when proxying relative redirects [1]. I need to debug more to see if I can reproduce this in php, but meantime a workaround may be to use an absolute url in the redirects if possible.

[1] details: #819 (comment)

[apedicdev]

thank you, we will try to implement your proposed workaround, but as far as i know in the magento rewrite table there's not the protocol choice

@apedicdev question: which version of ngx_pagespeed is installed?

[apedicdev]

hello, the version installed is
ngx_pagespeed-module-1.9.32.13

thanks

@apedicdev This issue was fixed in 40c05b4 which was included since v1.10.33.0-beta

So you could:

• Cherry-pick 40c05b4 (hopefully it applies cleanly)
• Upgrade to a later version. My advice would be 1.11.33.2 as it is build against the latest stable release of the PageSpeed optimization libraries
• This issue aside, I would recommend upgrading to at least 1.9.32.14 - see [1]

Closing this issue, but please re-open if it turns out none of the options above fixed the problem.
