Hide/strip set cookies on static files and howto use alias

Hi
I have a few questions about how do I configure it.

First question:

How do I strip the “Set-Cookie” header from all static files like css
and
jpg? I know i can setup a reverse proxy and use “proxy_hide_header
Set-Cookie”, but seems like foolish to make yet another host, just to
reverse to your self and add a few hundred msec to the request.

Second question:

I’m trying to make an alias to hide a folder in the lookup to the
subfolder,
the structure is:
/var/www/domain.tld/media/ads
/var/www/domain.tld/media/galleries
/var/www/domain.tld/media/misc
/var/www/domain.tld/media/thumbs

making the url like this /media/thumbs/5 subfolders/image-file

how do i change that into /thumbs/5 subfolders/image-file

I have tried with both alias and root but both returns a 404

Third question:
[error] 9178#9178: *13452 upstream timed out (110: Connection timed out)
while reading response header from upstream, client: upstream:
“fastcgi://unix:/var/run/php-fpm.sock”, host:

have a lot of those, any suggestions?

## Nginx’s Open file cache

https://easyengine.io/tutorials/nginx/open-file-cache/
open_file_cache max=5000 inactive=5m; ##If you have way
too
many files, change max from 5000 to more appropriate value.
open_file_cache_valid 20m; ## Tell nginx to check if information
it
is holding is valid every n minutes.
open_file_cache_min_uses 1; ## If files don’t change much often,
or
accesses less frequently, you can change inactive duration from 20m to
something else.
## Inactive
andopen_file_cache_min_uses works together.
## This sample tells nginx to cache a
file information as
long as minimum 2 requests are made during 5m window.
open_file_cache_errors on; ## Tell nginx to cache errors like 404
(file not found). If you are using nginx as load-balancer, leave this
off.

Hi Francis D. thank you very much for your reply

Let’s brake this down one by one. I followed you suggestion and added
fastcgi_connect_timeout 600s; to the conf, however the pages still time
out
after ~75 sec as expected do to this
http://nginx.org/en/docs/http/ngx_http_fastcgi_module.html#fastcgi_connect_timeout
“Defines a timeout for establishing a connection with a FastCGI server.
It
should be noted that this timeout cannot usually exceed 75 seconds.”

Hi there,

I have a few questions about how do I configure it.

It’s worth making sure that you are aware how nginx works, which is
(very briefly and roughly):

  • one request is handled in one location{}
  • only the configuration in, or inherited into, that location matters
  • inheritance is typically by replacement, or not at all
  • directives from the “rewrite” module can interfere with the above
  • documentation for “location” is at http://nginx.org/r/location

First question:

How do I strip the “Set-Cookie” header from all static files like css and
jpg? I know i can setup a reverse proxy and use “proxy_hide_header
Set-Cookie”, but seems like foolish to make yet another host, just to
reverse to your self and add a few hundred msec to the request.

Where does the “Set-Cookie” header come from? Default nginx does not
add it.

Can you create a small configuration which shows the problem?

Copy-paste the configuration and a “curl -v” request and response to
show the Set-Cookie header; that should make it more obvious what needs
to be fixed.

how do i change that into /thumbs/5 subfolders/image-file

For anything involving “root” or “alias”, the questions to consider are:

  • what file on your filesystem do you wish to fetch?

  • what url do you wish to use, to fetch that file?

And just in case it is not immediately obvious from those answers:

  • what is the intended mapping between url and filename?

With that information, it may become clear what “root” or “alias”
directive to use in the “location” that handles the request.

For the above, I suspect that “root /var/www/domain.tld/media;” may be
what you want, in the location{} that handles these requests.

I have tried with both alias and root but both returns a 404

What does the error log show?

Usually it shows the request, and the filename attempted, for a 404.
That
may give a hint at what configuration should be used.

What request did you make? What location{} did you put your root or
alias directive in?

Third question:
[error] 9178#9178: *13452 upstream timed out (110: Connection timed out)
while reading response header from upstream, client: upstream:
“fastcgi://unix:/var/run/php-fpm.sock”, host:

have a lot of those, any suggestions?

Either: ask your fastcgi server why it is slow to respond
(check its logs); or ask nginx to wait longer before giving up
(http://nginx.org/r/fastcgi_read_timeout).

These are the “location” definitions that you show:

location / {
location /thumbs/ {
location /admin/ {
location ~ \.mp4$ {
location ~ \.flv$ {
location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|xml)$ {
location = /50x.html {
location ~ \.php$ {
location ~ /\.ht {

For each test request that you make, which location block have you
configured nginx to use to handle it? Is that the one that you want
nginx to use to handle it?

Good luck with it,

Hi Francis, and of course everyone else

Another Q

Hi do have this in my domain.conf

location /admin {
  index index.php;
  access_log off;
  log_not_found          off;
  expires        0;
}

but yet, everything is logged? do you have some kind of answer to this?

In nginx, a http request is logged in the location where it ends.

So your “everything” request is not finally handled in the location that
you show. (Or you’ve found a bug in nginx.)

If it is not clear to you which location{} is used for the request,
and what subrequest is made, and which location{} is used for that
subrequest; then possibly enabling the debug log on a test server will
help you track it.

Note - the debug log contains lots of information, most of which
probably
counts as “noise” for the one specific thing you are trying to find.

You may want to read the previous mail again. I’m pretty sure I did not
mention fastcgi_connect_timeout.

You have nginx as the client, talking to your fastcgi(php) server. This
log file suggests that the fastcgi server is not writing to nginx
quickly enough.

The default nginx timeout is (I think) 60 seconds between reads. That
is usually suitable for fastcgi responses.

If your fastcgi server should be able to respond within that time, then
the problem you must address is why your fastcgi server is slower than
it should be.

If your fastcgi server is one of the few that has good reason to respond
more slowly than the nginx default timeout, then you must learn from
your fastcgi server how long it will take before it responds (at least,
for these requests); and then configure nginx to be willing to wait that
long (for these responses).

Nothing on the nginx side will determine how long it takes your fastcgi
server to respond. You must know how long that is; and configure your
nginx appropriately.

(If your php script starts with “sleep(100)”, for example, it will
probably take it at least that long to write something. If it needs to
do that sleep, then you need to configure the client to be willing to
wait that long.)
