I am trying to make apache2 use a default site when a user access my server by IP address, instead of inputing the site's domain, just to tell the user he cannot access the ip directly.

What is happening is that it keeps redirecting to the domain's site, overwriting the IP address in the browser, instead of showing the default site.

Note the domain's site is redirected to https, this is expected. The default site is not using ssl at all, and preferably should not use ssl.

My sites config are as folow (without logging, error documents nor ssl pathes directives): 000-default.conf

I have a pair of Ubuntu dedicated servers...

Server1:

I keep getting 403 forbidden access error when trying to access any project within htdocs folder. I even downloaded a vanilla CodeIgniter 3 project and got the same result. I'm using apache 2.4.

Above are my conf files.

httpd.conf:

I will have an event with 3k users on an app (php base).

I launch several instances in the cloud and install LAMP on it.[to make load test and choose on for the event]

On Ubuntu 18

I enable mpm_event and php7.4-fpm, (which seems to be the better configuration for high traffic with apache and php app).

I use this post which explain how tune your conf. Like this :

Here apache2 mpm event conf :

I use Laragon to run my sites on Windows and create a virstual host for each site and all the virtual hosts are working properly now. But recently I created a new virtual host but the index.php file is downloaded instead of running. Not all the solutions on the internet worked for me, because the rest of my virtual hosts work properly.

my site config

I have a DigitalOcean droplet running Ubuntu.

On it, I host three sites using Apache. I am trying to add a fourth, "newsite.com", swapping from another host. This fourth site is live on another environment with SSL enabled.

The existing three sites run fine. They have SSL enabled using LetsEncrypt and I use virtual hosts to set up multiple domains with the same IP. However, for the fourth one, the new site, if I try to view the site (by editing my Win10 hosts file to point at the server IP) I see one of the other three sites, "oldsite1.com", which is the highest in the list sorted alphabetically. I understand Apache works its way down the list of enabled sites to select one. The new site does not have SSL enabled as I cannot run LetsEncrypt until the DNS has been changed.

The .conf file for the new site looks like this:

I am going nuts.

This works, when the python module is in the same folder:

My issue is I am not sure how to type the code to increment trainADistance by trainAMPM and decrease trainBDistance by trainBMPM in the do loop while having each text appended to the list. Each minute is supposed to be appended individually with text += "Minute " + i + " Train A Position: "+ parseFloat(trainADistance).toFixed(2) + " miles" + "Train B Position: " + parseFloat(trainBDistance).toFixed(2);. An example is listed below. Any help would be appreciated.

What the function is supposed to do?

The function I have been attempting to create is supposed to allow the user to input three variables trainAMPH, trainBMPH and distanceApart. When the inputs are submitted, the function function calculateTrains() is supposed to calculate trainAMPH, trainBMPH into miles per minute trainAMPM and trainBMPM. There is a do-while loop in place to increment the minutesi , increment trainADistance by trainAMPM and decrease trainBDistance by trainBMPM. trainBDistance is supposed to contain the same value as distanceApart. The loop continues while(trainADistance < trainBDistance) and is supposed to append text into a list until the loop is broken. An example is listed below.

This is an example of what is supposed to be appended to to the list with inputs 70 for train A, 60 for train B and 260 for distance

I have found several similar questions:

• APACHE, PHP Server return randomly empty response
• https://serverfault.com/questions/66662/apache-gives-empty-reply
• and others

However these does not seem to help to find the cause. I can replicate the behaviour when reloading a specific page ~20 times.

1. Running current apache2 (= 2.4.38-3+deb10u4). I tried to disable opcache, remove MaxRequestsPerChild with no effect.
2. Apache log does not show any error. The request is not even logged.
3. The USE_ZEND_ALLOC=0 seem to have no effect and the problem persists.
4. I tried to install mod_forensic which shows that the request came in. No error or finished request is then logged.
5. The container is running in Kubernetes and I cannot replicate the issue locally running directly with Docker machine, that is why I think this might be caused by some memory setting. However I couldn't find what might be causing this as there is no single error message.

Can you think of any reason why this might be happening?

Edit1:

I tried to set log level to trace:

The request is handled and then you can see:
