Google Search Console – Reverse Proxy in IIS has implications for SEO in some way

I am creating a website with Angular and have enabled server-side rendering using the node js server.
Our site is hosted on an IIS server. To get content from Node Server, we use a reverse proxy (Application Request Routing AAR). Let me know.

To my knowledge, this is not a 302 redirect, so the overall ranking and traffic sap will not be affected.

Nodejs pnp-auth (adfs) behind the enterprise proxy

We have a Node / Express app that connects to SharePoint onprn via pnp-auth and node-sp-auth-config.
(IE connection settings: automatic)
Works great

Move this app to another server
On this server, the IE connection must be in the manual proxy configuration to allow the browser to connect to SharePoint

For the Node app, the result is: The Node app can not connect to SharePoint
"FetchError: request to ….. failed, reason: connect ETIMEDOUT …..: 443
to customer specification. (d: NODE QOMV-CRExport node modules pnp-auth node modules node fetch lib index.js: 1444: 11)

at emitErrorAndCloseNT (intern / streams / destroy.js: 50: 3)

Anyone any hints on how to solve this?

Thank you very much

How can I effectively optimize Apache + Nginx reverse proxy?

Hello everyone,

There are many useful tips and tricks to optimize performance and optimize the Apache or Nginx web server.

However, I could not find a recommendation for optimizing Apache + Nginx as a reverse proxy for maximum performance.

For example, I see many people recommending disabling Apache's DNS lookup, but if Nginx is at the top, I'm not sure if disabling Apache's DNS lookup has any value.

Which webserver should I further optimize in the Apache + Nginx setup? Apache or Nginx or do I have to do both at the same time?

Would you share your best optimization tips?

Linux – Nginx-based multi-site reverse proxy setup

I'm trying to set up an Nginx frontend ( for two servers. --> -->

If I do that, only the index.html is loaded, but Nginx looks in its local root for the static files (.js, .css, images).

For example a .css Request looks like this:

Instead of

I do not want to change that (I can not do that) base_url my apps.

My current configuration is:

location /airflow01/ {

debian – Squid proxy blacklisting + auth does not work

At the moment I have this configuration:

acl modems dst
acl modems dst

acl mypc src

http_access allow modems mypc
http_access allow modems localhost
http_access allow !modems
http_access deny all

I am trying to block access to and for all except localhost and my PC.

In addition, I configured an authentication like this

auth_param basic program /usr/lib/squid/basic_ncsa_auth /etc/squid/passwd
auth_param basic realm proxy
acl authenticated_users proxy_auth REQUIRED
http_access allow authenticated_users
# http_access allow localhost
http_access deny all

Allowing localhost to be unauthorized is convenient but not required. The problem is that if the first configuration snippet is not commented out, auth will not work, I just will not be asked for creds. But when it's commented out, auth works fine. I need both to work. How do I do that?

Chrome for easy proxy switching on Linux

I know the answer might be no, but is there an easy way to change the proxy for Chrome on Linux? Finally, I want certain sites to use proxy at the same time, while other sites do not.

I even tried launching Chrome from a command line with a different profile, but found that the previous proxy is still in use (checking its IP address).

I know the answer might be no, but I think it would not hurt to ask and confirm. Thank you very much. | CloudFlare Proxy – Pre-order now for $ 9.99 – Anti-DMCA & Privacy Policy WJunktion

Hello everybody,

I hope you are doing very well.

Take a deep breath and increase your focus level to the maximum. We're here to draw your attention to the biggest game changer in the industry.

We are here to guide you to our new project, which has been founded after more than 10 years of experience, which we have specially collected GO Unlimited and DropAPK, Most people wondered how DMCA ignored services like GO Unlimited and DropAPK Survived in these years without being taken down or losing any of our data.

We're not here to set up dedicated server hosting or web hosting solutions or basic physical solutions.

Over the last 3 years, many hosts have been trying to offer resources ignored by DMCA, including shared hosting, VPS and dedicated servers. The only reason they used word (ignored by DMCA) is marketing, While cheap DMCA ignored services were ultimately not DMCA ignored, the true DMCA ignored services were extremely expensive.

It was as follows: If you have the money, your privacy is protected, but if you do not, let's sell some of your inflation to close the financial gap! This is not a joke, but a real fact.

That's why we decided to offer Clou RiderAiming to provide a 100% secure proxy for all types of websites that will ensure their stability and protect the privacy of the site and its owners from all types of reports and requests for information when used with DMCA or similar laws This can be used to violate the privacy of the website owner. Clou Rider provides a solution that allows webmasters who regularly use cheap hosting services such as, OVH and Godaddy or other hosts around the world to protect their websites from DMCA and information requests. As? Simply, because nobody would know which host is their origin.

Nobody can find the hosting service your website uses because CloudFlare itself is unable to identify it. The only information that CloudFlare receives about your website using our IP address and displaying our shipping notification.

Q: What happens if CloudFlare receives a DMCA report to my website?

A: CloudFlare passes the report on to us and assumes that we are your web hosting service.

How does the actual service work?

For example, suppose you buy the CF proxy image from the following address:

Of course, you will complete the payment process and receive a confirmation e-mail, right? Then wait for the service to be delivered within 24 hours.

Within 24 hours, you will receive an IP address associated with your web site that will be the primary IP address in your CloudFlare DNS for that domain.

For example, the IP address associated with your website is Then you need to log in to your CloudFlare login page:

You must now replace the main IP address of the domain with the one provided by us. Each website will be given a different unique IP address.

How to cancel? Well, this is one of the few services that you can cancel yourself without contacting us! You can simply edit the main IP in your domain DNS and replace our IP directly with your originating server IP.

This picture describes the service system:

Since we are just setting up the service, we offer a lifetime 50% discount for pre-orders. You can now pre-order the service at half price and extend the service forever with the same discount.

Pre-order now:

Feel free to send us a comment if you need more information.

vue.js – The proxy setting of Vue.config.js is not ported to another port number

I'm running vue-cli in development mode on port 8080. I call via API port 8081.
To make an API call, I've updated my vue.config.js file as follows:
