Hi

For one user on a server, visitors have a lot of 400 Bad Request.
I don't find why.

If I open too quickly several pages, I've this error 400
I don't know where to search now.

I use CSF firewall, but same problem when I disable it.

Configuration :
php 5.6
ServerAlias *.|DOMAIN| in httpd.conf customisation



It's seems there is a limitation in the user... but I don't see any limit.

If I navigate on another domain (other user account) in the same server, no problem.




So, how to investigate ?
Thanks for your help.

Is it only 400 or 400.1 or 400.2 or something like that?

It can be several things.

ServerAlias *.|DOMAIN| in httpd.conf customisation
Explain this please. Did you make some kind of customisation yourself? Is this only for this domain?

You might want to have a look in the log if you can find more there.
/var/log/httpd/error.log
/var/log/httpd/domains/userdomain.error.log
/var/log/httpd/domains/userdomain.log

Hi

Thanks for your reply.
How to see if it's 400.1 or else ?
I see only 400 on the message.

=> ServerAlias *.|DOMAIN| in httpd.conf customisation
It's for accept all subdomain, without create them.
(it's a web service, where all customers have their own subdomain).

=> /var/log/httpd/error.log
nothing (i've error page, without any new line in it)

=> /var/log/httpd/domains/userdomain.error.log
only one line with error 400

=> /var/log/httpd/domains/userdomain.log
nothing (i've error page, without any new line in it)
