Using HTTP and HTTPS proxies with Camel HTTP Component
I'm writing some test code which uses and HTTP/HTTPS proxy to mock 3rd
party webservices.
For non-camel code, I configure the proxy using the java system properties:
http.proxyHost, http.proxyPort, https.proxyHost, https.proxyPort,
http.nonProxyHosts.
These settings seem to be ignored by camel, so I have also explicitly
set the HTTP proxy in camelContext (code is groovy):
camelContext.properties['http.proxyHost'] =
System.properties['http.proxyHost']
camelContext.properties['http.proxyPort'] =
System.properties['http.proxyPort']
These settings work fine *for HTTP*. However, I can't find
documentation for getting HTTPS working.
I've tried setting other properties on the camel context, such as
https.proxyPort, http.proxyScheme, http.proxyAuthSceme,
https.proxyScheme, https.proxyAuthScheme to no avail (although I've
seen a couple of different exceptions).
I'd be happy to document my findings, but thought I should first check:
* is this a known issue?
* has it been fixed in later version of camel? (I'm using 2.9.4)
* should I expect to be able to proxy both HTTP and HTTPS to either
different or the same ports using Camel without reconfiguring in
between requests?
Thanks for any help,
Alex

Thanks for the pointers - will probably give this a go next week.
As I'm using this to mock 3rd party services for a camel-based system
under test, changing endpoint URLs is not convenient, but it's very
helpful to know that other methods do not work.

Alex,
As Christian M. points out, use the camel config on the endpoint, not the
way you're doing in your OP.
Cheers

I mean something like this [1].
As I understood your post, you try to achieve this by setting system
properties and/or camel context properties...

Hi Christian,
Thanks for the suggestion. Do you mean something other than what I
referred to in my original post?

Did you tried setting the proxy host/port as we described here [1]?
