I have got VisualSVN installed in a test server but the `conf` file warns against modifications and web searches have provided no hints except links to an apparently defunct Trac plugin [1] including the comment "The new web browser is powered by HTML5 and ensures easy integration with third-party issue trackers" and a version of the svn book[2]

Here are the basic steps. The main idea is to modify httpd-custom.conf
file instead of httpd.conf.

1. Modify "%VISUALSVN_SEREVR%conf\httpd-custom.conf" file instead of

2. Load mod_wsgi module by adding the line to the httpd-custom.conf.
   LoadModule wsgi_module bin/mod_wsgi.so

3. Generate the trac.wsgi script by running `tracadmin deploy` and
   specify WSGIScriptAlias directory in httpd-custom.conf pointing to
   trac.wsgi file.

4. Add the desired <directory> configuration to httpd-custom.conf

   Generally speaking, the steps and some examples are specified on
   the Trac wiki page: https://trac.edgewall.org/wiki/TracModWSGI.

NOTE: The latest version of Python 2.7 is 2.7.11 and it has a bug in
its installer on Windows. See https://bugs.python.org/issue25824. The
problem may cause service load failures when loading `mod_wsgi`. The
workaround specified at https://bugs.python.org/msg256500 should solve
the problem. In short, after installing Python 2.7.11 you should
adjust the Windows Registry key mentioned in the workaround. The bug
has to be solved in the upcoming Python 2.7.x patch update AFAIK.
