This addresses #18, which brought up the issue of searching with Whoogle
with the search instance set to always use a specific container in
Firefox Container Tabs.
Could also be useful if you want to share your search results or
something, I guess. Though nobody likes when people do that.
Added <meta name="referrer" content="no-referrer"> to all whoogle
templates
Refactored search route to use conditionally use either request.args or
request.form, depending on rest call (get vs post respectively)
The implementation of POST search support comes with a few benefits. The
most apparent is the avoidance of search queries appearing in web server
logs -- instead of the prior GET approach (i.e.
/search?q=my+search+query), using POST requests with the query stored in
the request body creates logs that simply appear as "/search".
Since a lot of relative links are generated in the results page, I came
up with a way to generate a unique key at run time that is used to
encrypt any query strings before sending to the user. This benefits both
regular text queries as well as fetching of image links and means that
web logs will only show an encrypted string where a link or query
string might slip through.
Unfortunately, GET search requests still need to be supported, as it
doesn't seem that Firefox (on iOS) supports loading search engines by
their opensearch.xml file, but instead relies on manual entry of a
search query string. Once this is updated, I'll probably remove GET
request search support.
