Duplicate Location headers after 302 redirects

[HansVanEijsden]

After doing a 302 redirect, browsers like Safari Desktop and Safari Mobile can't display the page. Probably because of duplicate Location headers.
The problem also occurs after trying to login to Wordpress, RoundCube webmail or Joomla (all of those give redirects after a successful login).

To replicate:

$ curl -I https://www.fundays.nl
HTTP/1.1 302 Moved Temporarily
Server: nginx
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
Keep-Alive: timeout=300
Set-Cookie: wb_4647-sid=0r1guonnvfl6sa861oh3noc055; path=/; HttpOnly

Access-Control-Allow-Origin: *
Strict-Transport-Security: max-age=31536000;

Date: Fri, 22 Jan 2016 15:46:48 GMT
X-Page-Speed: 1.10.33.2-7600
Cache-Control: max-age=0, no-cache

$ curl -I https://www.fundays.nl?ModPagespeed=Off
HTTP/1.1 302 Moved Temporarily
Server: nginx
Date: Fri, 22 Jan 2016 15:45:15 GMT
Content-Type: text/html; charset=UTF-8

Access-Control-Allow-Origin: *
Strict-Transport-Security: max-age=31536000;

Tested with ngx_pagespeed 1.10.33.2-7600 on Nginx 1.9.9.
Basic Nginx config (without Pagespeed parts): http://pastebin.com/FtDdGTeX

If you need the Pagespeed config parts, just let me know. The problem also occurs with all the Pagespeed filters disabled (but Pagespeed loaded of course).

Consider 1f02f36 and its re-application later on for 1.10 01e458c

They look different, which may need closer inspection

[oschaaf]

No this seems to be a dead-end, I can't spot a problem with 1f02f36 vs 01e458c

[oschaaf]

Oh wait, but 01e458c was added fairly recently and is not available in 1.10.33.2

[jeffkaufman]

Otto noticed that 059dd20 didn't make it into 1.10 because it was merged to the wrong place. That's probably it.

[HansVanEijsden]

Hoping for it. Thanks!

[jeffkaufman]

@HansVanEijsden Would you be able to try cherry-picking 059dd20 to verify that this fixes it?

[HansVanEijsden]

@jeffkaufman I would love to, but I can't find the instructions on how to install from source.
https://developers.google.com/speed/pagespeed/module/build_ngx_pagespeed_from_source only mentions downloading the zip file, unfortunately..

[jeffkaufman]

Sorry about that! Here's up to date instructions for building from git:

Where it says:

wget https://github.com/pagespeed/ngx_pagespeed/archive/release-${NPS_VERSION}-beta.zip \
     -O release-${NPS_VERSION}-beta.zip
unzip release-${NPS_VERSION}-beta.zip

Instead do:

git clone git@github.com:pagespeed/ngx_pagespeed.git
mv release-${NPS_VERSION}-beta release-${NPS_VERSION}-beta-old # in case you have one already
mv ngx_pagespeed release-${NPS_VERSION}-beta

Then after you do cd ngx_pagespeed-release-${NPS_VERSION}-beta/, run

git checkout release release-${NPS_VERSION}-beta

Now's the place for the cherry-pick:

git cherry-pick 059dd20

And then continue on with the rest of the build, starting with wget https://dl.google.com/dl/page-speed/psol/${NPS_VERSION}.tar.gz

[HansVanEijsden]

No need to say Sorry Jeff. I never asked about it before. 😉

Unfortunately I encounter some errors. I tried to correct them as far as possible, but I'm stuck at doing the right git checkout. Here are the steps I've done (system language is in Dutch, nl_NL, sorry):

[jeffkaufman]

Whoops, I had a typo. Instead of:

git checkout release release-${NPS_VERSION}-beta

you should have

git checkout release-${NPS_VERSION}-beta

[HansVanEijsden]

Good news: I love those cherry-picks! 😄
Up & running and working without problems.

In Safari, Wordpress logins and all the other stuff is also working again like it should.
Good to go! 😃

[crowell]

the git checkout command should be

git checkout release-1.10.33.2-beta

@jeffkaufman I think we should test for duplicates of some headers so we make sure we don't regress, some of the header manipulation in nginx is excessively tricky. Should I create a new issue for that?
