Where is the documentation for HttpClient 4.1.x?

Question

Where is the documentation for HttpClient 4.1.x?

I just want something like http://hc.apache.org/httpcomponents-client-4.4.x/index.html(4.4.x's documentation)

My sad story

I'm going to use HttpClient 4.1.x, and can't upgrade to 4.3.x or 4.4.x because the parent module (which calls my module) uses 4.1.x. This is a typical problem in large companies.

First things first, I wanted to find the documentation for HttpClient 4.1.x, so I opened the home page of HttppClient:

http://hc.apache.org/

But in the navigation I can only find documentation for 4.3 and 4.4. I looked for something like Older Versions or Version List, but I couldn't find anything.

Then I tried searching (Google) and found the 4.2.x homepage. I hoped this might link to 4.1.x documentation, but no luck.

http://hc.apache.org/httpcomponents-client-4.2.x/index.html

I'm good at learning patterns, so I guess 4.1.x's homepage is:

http://hc.apache.org/httpcomponents-client-4.1.x/index.html

But, again, disappointment:

Fortunately, the Wayback Machine can get you the archived site: https://web.archive.org/web/20120103180744/http://hc.apache.org/httpcomponents-client-ga/index.html

The (pretty clumsy) alternative would be to build it yourself:

1. Check out HttpClient: svn co http://svn.apache.org/repos/asf/httpcomponents/httpclient/tags/4.1.3 httpclient
2. Build HttpClient's site, skipping subprojects: mvn -pl . site (the subprojects contain missing dependencies)
3. The build will still fail, but it will get far enough to generate HTML and PDF documentation in target/site, including a big tutorial PDF.

That worked for me, although it's a pretty clumsy process.
