I can easily see this in my browser:
I can also see the same with cURL's verbose flag:
curl -v https://rustymagnet3000.local/hello

I'm trying to get Go to use an internal enterprise Go-Proxy for module download - which requires an http_proxy to be accessible (enterprise firewall). However go get -u golang.org/x/lint/golint fails:
package golang.org/x/lint/golint: unrecognized import path "golang.org/x/lint/golint": https fetch: Get "https://golang.org/x/lint/golint?go-get=1": Forbidden
My setup:
http_proxy and https_proxy environment variables are set
no_proxy does not contain the IP or hostname of my Go-Proxy
GOPROXY is set (go env -w GOPROXY=https://artifactory.mycompany.com/api/go/myrepo-go-virtual)
I checked:
Using curl and directly querying the GOPROXY server works fine and I can download the file (so the https_proxy setting works)
Counter-check with curl and explicitly unsetting http/https_proxy: No connection, as expected
Using tcpdump, I discovered that running go get seems to ignore my GOPROXY and ask my http_proxy to connect directly to the original url on golang.org (Options/sequence and ack numbers omitted for brevity), which the proxy/firewall blocks.
06:52:53.926397 IP <my_ip.port> > <proxy.port>: Flags [S], length 0
06:52:53.927206 IP <proxy.port> > <my_ip.port>: Flags [S.], length 0
06:52:53.927232 IP <my_ip.port> > <proxy.port>: Flags [.], length 0
06:52:53.932003 IP <my_ip.port> > <proxy.port>: Flags [P.], length 89: HTTP: CONNECT golang.org:443 HTTP/1.1
06:52:53.932638 IP <proxy.port> > <my_ip.port>: Flags [.], length 0
06:52:53.933100 IP <proxy.port> > <my_ip.port>: Flags [P.], length 3939: HTTP: HTTP/1.1 403 Forbidden
Question: Why does Go ignore the GOPROXY? Did I not set something up correctly?
I'm using Go 1.15.3 in the golang:1.15.3 Docker container (with some added tools to check connectivity)
Try this: set GO111MODULE=on to use GOPROXY
Or run go mod init before you run go get
The following command works fine serving up a web page with a profile and I am able to analyse it, very good.
go tool pprof -http=:8082 https://mytestserver.net:443/debug/pprof/profile?seconds=3
However if I try a trace, this happens
$ go tool pprof -http=:8082 https://mytestserver.net:443/debug/pprof/trace?seconds=3
Fetching profile over HTTP from https://mytestserver.net:443/debug/pprof/trace?seconds=3
https://mytestserver.net:443/debug/pprof/trace?seconds=3: server response: 404 Not Found - Unknown profile
failed to fetch any source profiles
This doesn't work either
$ go tool trace -http=:8082 https://mytestserver.net:443/debug/pprof/trace?seconds=3
2020/09/29 22:34:49 Parsing trace...
failed to open trace file: open https://mytestserver.net:443/debug/pprof/trace?seconds=3: The filename, directory name, or volume label syntax is incorrect.
Was following some examples from
https://jvns.ca/blog/2017/09/24/profiling-go-with-pprof/
Trace could be useful to visualize GC behaviour as well as Goroutine/Threads etc.
Is there another way to generate trace?
I run trace from a Windows machine and the following is the versioning info
$ go version
go version go1.15.2 windows/amd64
Did you tried using http instead of secure connection?
It seems it only works for http connections FYR.. https://golang.org/pkg/net/http/pprof/

I suspect the problem is with "https": the SSL/TLS handshake is failing.
If you connect to an HTTPS site with a web browser, you use the browser's trust store (very often, this is one-in-the-same as your desktop's Windows trust store).
SUGGESTIONS:
Verify your "test.sh" works from the command line.
Modify your script to run wget --debug --trace ..., and check the output.
If only for troubleshooting purposes, try --no-check-certificate, too.
Look here for more details:

When I am using the websphere console, and navigate to the Secure Administration -> SSO I have a checkbox called: 'Require SSL'. How do I enable/disable this using jacl/jython ?
I have even used the command assistance from the console. But when I checked the logs, I can see almost every other command being issues apart from this setting.
Using Jython:
AdminTask.configureSingleSignon('-requiresSSL true')
Other available options for the configureSingleSignon command:
-enable [true|false]
-domainName [String]
-interoperable [true|false]
-attributePropagation [true|false]
Reference: SecurityConfigurationCommands command group for the AdminTask object.
I'm trying to get Selenium to work with Magento TAF in Netbeans off a Wamp Server. When I run the test I get the following error:
Call to undefined function curl_init() in
C:\wamp\bin\php\php5.4.3\pear\PHPUnit\Extensions\SeleniumTestCase\Driver.php
on line 995
When I try and do a google search I keep getting results saying to enable curl, which is pointless for me because I do have it enabled. Have had it enabled for quite some time. The information in from the phpinfo for the curl section is as follows:

and on that line i have

Any ideas what's going on?
It appears that your IDE is referencing one php.ini, whilst when you run your tests on your WAMP server, it is referencing another.
Either:
a) Make sure you are using the same pho.ini file between the IDE and the WAMP server, or;
b) Make sure all php.ini files have extension=php_curl.dll uncommented.
