I currently have two apps at AppFog, they are.
http://sru-forums-prod.aws.af.cm/ and http://sru-home-prod.aws.af.cm/
I have haProxy running locally on my computer, this is my current config file.
global
debug
defaults
mode http
timeout connect 500ms
timeout client 50000ms
timeout server 50000ms
backend legacy
server forums sru-forums-prod.aws.af.cm:80
frontend app *:8232
default_backend legacy
The end-goal is that localhost:8232 forwards traffic to sru-home-prod, while localhost:8232/forums/* forwards traffic to sru-forums-prod. However I cant even get a simple proxy up and running.
When I run HAProxy off this config file I receive AppFog 404 Not Found at localhost:8232.
What am I missing, is this even possible?
EDIT:
New config works but now i have a port 60032 coming back in the response.

The reason you are getting an AppFog 404 Not Found is because applications hosted on AppFog are routed by domain name. In order for AppFog to know what app to serve you, the domain name is required to be in the HTTP request. When you go to localhost:8232/forums/ it sends localhost as the domain name which AppFog does not have as a registered app name.
There is a good way to get around this issue
1) Map your application to a second domain name, for example:
af map <appname> sru-forums-prod-proxy.aws.af.cm
2) Edit your /etc/hosts file and add this line:
127.0.0.1 sru-forums-prod-proxy.aws.af.cm
3) Go to http://sru-forums-prod-proxy.aws.af.cm:8232/forums/ which will map to the local machine but will go through your haproxy successfully ending up with the right host name mapped to your app hosted at AppFog.
Here is a working haproxy.conf file that demonstrates how this has worked for us so far using similar methodologies.

I'm trying to code a chat with Symfony 5 and Mercure, but I have some issues with the configuration. I work with Windows 10.
This is the documentation that I followed : https://github.com/dunglas/mercure/blob/main/docs/hub/install.md
I installed this version on my project: mercure_0.13.0_Windows_arm64.zip.
Then, I decompressed it, and right after in my terminal, I ran "composer require symfony/mercure".
This is in my .env:
# See https://symfony.com/doc/current/mercure.html#configuration
# The URL of the Mercure hub, used by the app to publish updates (can be a local URL)
MERCURE_URL=:https://127.0.0.1:8000/.well-known/mercure
# The public URL of the Mercure hub, used by the browser to connect
MERCURE_PUBLIC_URL=https://127.0.0.1:8000/.well-known/mercure
# The secret used to sign the JWTs
MERCURE_JWT_SECRET="!ChangeMe!"
###< symfony/mercure-bundle ###```
Then I ran the Mercure server with this command line : ```$env:MERCURE_PUBLISHER_JWT_KEY='!ChangeMe!'; $env:MERCURE_SUBSCRIBER_JWT_KEY='!ChangeMe!'; .\mercure.exe run -config Caddyfile.dev```.
In my PowerShell, I have this :
```2021/11/16 01:39:58.029 INFO http server is listening only on the HTTPS port but has no TLS connection policies; adding one to enable TLS {"server_name": "srv0", "https_port": 443}

It seems to run well, but in my browser when I run ```https://localhost/.well-known/mercure```,
I have :
```Not Found
The requested URL was not found on this server.
Apache/2.4.46 (Win64) OpenSSL/1.1.1h PHP/7.4.25 Server at localhost Port 443```
Someone can help me because I don't know how to access to my Mercure server with my browser ?
Thank you very much
Hey ben you should try and run https://localhost:8000/.well-known/mercure in ur browser
instead of https://localhost/.well-known/mercure
Maybe you've allready figured out this problem in the last 3 months, but here are a thing it came to my mind.
You start Mercure 0.13 in dev mode (Caddyfile.dev) allowing to access the demo page.
(Btw I miss the log entry here which tells you, that the server uses the file specified by you, and should be something like {"level":"info","ts":1646214769.1484525,"msg":"using provided configuration","config_file":"/etc/caddy/Caddyfile.dev","config_adapter":""}) You may want to open this demo page to see if Mercure works or not. The default url is https://localhost/.well-known/mercure/ui/. It may vary depending on your settings. It worth to try also with http.
You don't provide the SERVER_NAME env variable, so I assume caddy attempts to use 80 and 443 ports. Therefore https://127.0.0.1:8000 in symfony config won't work. And 80 might fail if there is already a web server running to provide access for symfony.
You can use SERVER_NAME=:8000 to launch mercure on port 8000, but in this case it will be only http, not https.
So, what I would do in your case, I would start mercure in dev mode, and check the demo page. If both http and https attempts fail, I would start mercure with additional SERVER_NAME (ex. 8000) and check http://localhost:8000/.well-known/mercure/ui/. If nothing goes wrong, one of them should work. And then you can proceed to configure symfony to use the mercury service.
I'm calling php file via axios get method in vue cli 3.
my servers: node js and wamp server
My app (node) path http://localhost:8080/ &
my WAMP path http://localhost:80.
Now I got has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource and I saw https://cli.vuejs.org/config/#devserver-proxy but it's not working for me.
In my vue.config.js
module.exports = {
devServer: {
proxy: 'http://localhost/'
}
}
and my PHP file path in the views folder
http://localhost:80/blog/src/views/php/imageUpload.php
I need to know where I did mistake.
This is the error I'm getting:
And this is my code:
The CORS mechanism is used to enforce the client requests are coming from applications belonging to the same domain as the domain at which the server is deployed by default.In other words, it is to ensure that our own applications are only applications that access our API and to prevent applications belonging to other domains to access it. In your case, the Client application and Server application are using different ports. That breaks the rule
The requests are initiated from application running at 8080 to the server API running at 80, though they are running in the same localhost.The port differs. That's why the CORS errors are thrown.
Please set the header Access-Control-Allow-Origin to localhost:8080 in the your PHP application to allow the cross domain requests.
Please read the Functional overview of CORS mechanism here
I'm using haproxy to loadbalance and get high availability of my (RESTFUL)API, the problem I'm facing is: I can't send REST requests to the API.
I mean haproxy does not support REST API by default and I've figured that I should configure an ACL to make it work, but I couldn't find anything about configuring RESTFUL Support and enabaling http rewrite rules for haproxy.
MY API is based on laravel framework.
For example If I hit 192.168.1.139/login I get 404 error message. the only route which is working is / Which shows the user "you are not logged in." message.
This is haproxy configuration :
listen http_front
bind *:80
mode http
stats enable
stats uri /haproxy?stats
option httpclose
option forwardfor
#acl api_exp hdr(host) -i domain_name.com
#use_backend api_servers if api_exp
default_backend api_servers
backend api_servers
balance roundrobin
server replica1 192.168.100.110:80 check
server replica2 192.168.100.111:80 check
It's a bit strange but I've solved my problem with this configuration :
defaults
log global
mode http
option httplog
option dontlognull
retries 3
option redispatch
timeout connect 5000
timeout client 100s
timeout server 100s

I am running ubuntu with apache2, I have a php system that is working with rewrite rules - all is working perfect.
Recently, due to increasing traffic I added a load balancer (haproxy), this is the second time I am using haproxy so I am not a pro.
When working with the haproxy I see the the .htaccess rules are not working - accessing the pages without the rules stil works.
This is the haproxy.cnf:
global

I'm trying to create a live web server on my Windows 8.1 computer.
I am connected directly to my modem using ethernet (I do have a wireless router) but I am not connected to it on this computer (desktop).
I have XAMPP working and my website appears at http://localhost/home
However, if I put in my IP from www.whatismyip.com it does not load my web server.
What am I missing?
You need to create a Port Forwarding for Port 80 to your Computers local IP Address. There should be a Admin Panel for your Router (normally the Gateway - check out with Start - Run - cmd -> then insert "ipconfig" and check out the Gateway.
And i guess in XAMPP the Internet Access is blocked. But this is a simple Apache Server, so you need to open your httpd.conf File (Should be: “c:\xampp\apache\conf\extra\httpd-xampp.conf)
Search here for:
There should be a "Deny from all" - add a # in Front to deactivate that rule.
Restart your Xampp and it should work.
Here you find more Information about Port-Forwarding:
https://managewp.com/how-to-access-a-local-website-from-internet-with-port-forwarding
Any maybe you will also need to activate Port 80 on your Firewall (depends on your Configuration)
You need a method of telling request sent to your public ip to be forwarded to the private ip of the web server. Try logging into you device (router etc) and setting this up.
