Re: Strange redirections when pagespeed is on

[Jeff Kaufman]

Is it possible for you to log where they were redirected to?

It looks to me like that user's path was something like:

1) browsing fb on mobile

2) clicked link for http://www.saludterapia.com/articulos/generales/motivacion.html

3) loaded http://www.saludterapia.com/articulos/generales/motivacion.html with fb referer

4) eight seconds later reloaded page

5) they were immediately permanently redirected to http://www.saludterapia.com/eventos.html

6) they were immediately permanently redirected to somewhere unknown

So 1-3 are expected, and 4-6 are unexpected, right?

These aren't the kind of changes PageSpeed would typically make.

If you search your configuration files for the string "301" does anything come up?

Hi!

I'm having very strange redirections when pagespeed module is on. Some facts:

1. This happens once in a while (seems randomly)
   
2. When I restart apache (with pagespeed enabled) at the beginning everything seems to be working very well). Then, after 1 hour or so, I start to see the issue.
3. I can reproduce this behavior if I open a webpage using facebook mobile APP (it opens in a external browser) 

Here is the apache access.log opening the same page from facebook app several times. You can notice that in the third  run, there is a 301 redirect to the 4th entry line.

On pagemod message log I can't find anything suspect (no error message).

My pagespeed configuration is:

Here is my Apache config:

I'm a little bit lost here. If anyone could shine some lights on this I would appreciate. Thanks in advance.
