First, you might want to be aware of this apparent proxy bug that was discovered in Apache httpcomponents 4.2:|
It seems to be limited to NTLMv2 proxies...with authentication...so it may not be relevant to you, but it may be. We are trying to figure out what to do about it for Luna SR 1, as it seems to be caused by the change from using httpcomponents 4.1 in Kepler (no problem) to 4.2 in Luna.
Second, ECF filetransfer *optionally* uses the Eclipse proxy API config (if org.eclipse.core.runtime.net is present in framework). If it is present, then ECF filetransfer provider uses the proxy information across any/all filetransfer providers (httpcomponents 4, jre urlconnection). If the Eclipse proxy API is not present, then ECF falls back on using the JRE proxy config (i.e. the proxy.* Java system properties).
So if you didn't want to use IProxyService, you could simply leave out the org.eclipse.core.runtime.net bundle from your environment, and use the JRE system properties. Also, you can use either the httpcomponents 4, httpclient 3.1, or the jre/urlconnection-based provider, just by including or leaving out the appropriate bundles. For example, it may be that in your proxy environment the best thing would be the jre/urlconnection-based provider. ECF will fall back to using that provider if the httpcomponents 4 provider bundles are not present in a given framework (at runtime).
There's much more detail, obviously, but hopefully this can get a discussion started.
