I have a .net CF proxy that issues a POST like so:
POST http://192.168.0.172:8080/MIS.WOService/Service.svc HTTP/1.1
Content-Type: text/xml; charset=utf-8
SOAPAction: http://tempuri.org/IWOService/LogIntoServer
Content-Length: 276
Connection: Keep-Alive
Expect: 100-continue
Host: 192.168.0.172:8080
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><LogIntoServer xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/"><emp_pin>55555</emp_pin></LogIntoServer></s:Body></s:Envelope>
The calls always fail with the server returning:
HTTP/1.1 404 Not Found
Date: Thu, 09 Dec 2010 16:07:14 GMT
Server: Microsoft-IIS/6.0
X-AspNet-Version: 4.0.30319
Cache-Control: private
Content-Length: 0
However if, in fiddler I change the POST to a GET it works...
I have the configuration for the website to allow ALL verbs on the svc extension and the " verify file exist" is un-checked.
Does anyone know what could be causing this behavior by IIS 6 ?
When I inspect the IIS logs, it shows:

Apparently I needed to put the name as url as such:
http://192.168.0.172:8080/MIS.WOService/Service.svc/basic
and then the server started allowing the svc to receive the soap messages...
Thanks

I watched in fiddler what the wcfTestClient sent as requests...
http://192.168.0.172:8080/MIS.WOService/Service.svc/basic
and then the server started allowing the svc to receive the soap messages...

I have the following question. We are using net core 3.1.
We make a soap request (HttpWebRequest) to a external webservice where they only allow a whitelist of IP addresses into the portal. Our VPN Ipadress is in the whitelist.
But when i send a request (Via Visual studio debugger) it get rejected by de external webservice: 403 Unauthorized.
But when starting Fiddler and then sending the same request again, via Visual studio debugger, we get a 200 OK.
The same is with Postman. When fiddler is not running the request gets rejected. When Fiddler
is running the request is accepted and the response is 200 OK.
I dont understand what is happening, How to solve this.

*Let me know what other reports/resources could be helpful for resolving this issue. Thanks in advance for any help!
Old post but I manage to solve this error by increasing the timeout.
sudo nano /etc/varnish/default.vcl
and having the following config settings:
backend default {
.host = "127..0.0.1";
.port = "8080";
.connect_timeout = 600s;
.first_byte_timeout = 600s;
.between_bytes_timeout = 600s;
}
Although 600s as timeout is probably too much, you can have much lower setting which can work for you. For further help read this thread.
PS: I am on Ubuntu 14.04.
I guess Varnish can not talk to your backend. Maybe this can help:

I was actually able to solve this. My website is a WordPress website so it often that the system receives a brute force attack on the /wp-admin panel. But this time I also noticed the same memory and CPU > 90% alerts from New Relic.
So I ran netstat -natp | grep varnishto figure out which IP was attacking me.
then proceeded to permanently block the IP with my server firewall.
This resolved the issue. Hope this helps someone!
I'm using Apache2 to route incoming requests to backend python flask web service and Splunk web service, there are running on the same server. I need to use POST to upload my file.
Here's my apache proxy setup:
ProxyPass /api/ http://10.68.57.166:5000/api/
ProxyPass / http://10.68.57.166:8000/
The test shows POST request has not been successfully routed, GET request is working fine although, the message says the method is not allowed, because my python flask only allows POST and OPTIONS.
Please help give me some thoughts of how to get it fixed ? very appreciated.

I'm puzzled why this FE doesn't seem to connect me to the BE through my HAproxy:
defaults

frontend fe-kb
bind :8081 ssl crt /etc/haproxy/ssl/ssl-key.pem
default_backend be-kb
backend be-kb
server afnB afnB:1080 check
I get this in HA http log:

I can connect fine from HAproxy CLI (selinux is disabled):

Figured it out, the default route wasn't through my HAproxy and as I was trying to do transparency of the source IPs well ;)

'm trying to use the If-Modified-Since command in Telnet. I want to get a 304 Not modified statut code. I tried this but it don't work, I get a 400 bad request error

I got as a result

You need to define the HTTP port. So try:
telnet lemonde.fr 80
The default telnet port is 23. So you won't be able to communicate with the HTTP server.
