noVNC 1.3.0 beta

This space that was added here was added to the parsed value of the
query variable. This broke any comparisons with the value, for example
"myvar=true" resulted in a value of "true ".

This was broken by f796b05e42

The commit also adds unit tests for webutil.getConfigVar() that will
detect problems like this in the future.

+### Installation from Snap Package
+Running the command below will install the latest release of noVNC from Snap:
+
+`sudo snap install novnc`
+
+#### Running noVNC
+
+You can run the Snap-package installed novnc directly with, for example:
+
+`novnc --listen 6081 --vnc localhost:5901 # /snap/bin/novnc if /snap/bin is not in your PATH`
+
+#### Running as a Service (Daemon)
+The Snap package also has the capability to run a 'novnc' service which can be 
+configured to listen on multiple ports connecting to multiple VNC servers 
+(effectively a service runing multiple instances of novnc).
+Instructions (with example values):
+
+List current services (out-of-box this will be blank):
+
+```
+sudo snap get novnc services
+Key             Value
+services.n6080  {...}
+services.n6081  {...}
+```
+
+Create a new service that listens on port 6082 and connects to the VNC server 
+running on port 5902 on localhost:
+
+`sudo snap set novnc services.n6082.listen=6082 services.n6082.vnc=localhost:5902`
+
+(Any services you define with 'snap set' will be automatically started)
+Note that the name of the service, 'n6082' in this example, can be anything 
+as long as it doesn't start with a number or contain spaces/special characters.
+
+View the configuration of the service just created:
+
+```
+sudo snap get novnc services.n6082
+Key                    Value
+services.n6082.listen  6082
+services.n6082.vnc     localhost:5902
+```
+
+Disable a service (note that because of a limitation in  Snap it's currently not 
+possible to unset config variables, setting them to blank values is the way 
+to disable a service):
+
+`sudo snap set novnc services.n6082.listen='' services.n6082.vnc=''`
+
+(Any services you set to blank with 'snap set' like this will be automatically stopped)
+
+Verify that the service is disabled (blank values):
+
+```
+sudo snap get novnc services.n6082
+Key                    Value
+services.n6082.listen

-## Pre-conversion of Modules
+## HTTP Serving Considerations
+### Browser Cache Issue
 
-noVNC is written using ECMAScript 6 modules. Many of the major browsers support
-these modules natively, but not all. By default the noVNC application includes
-a script that can convert these modules to an older format as they are being
-loaded. However this process can be slow and severely increases the load time
-for the application.
+If you serve noVNC files using a web server that provides an ETag header, and
+include any options in the query string, a nasty browser cache issue can bite
+you on upgrade, resulting in a red error box. The issue is caused by a mismatch
+between the new vnc.html (which is reloaded because the user has used it with
+new query string after the upgrade) and the old javascript files (that the
+browser reuses from its cache). To avoid this issue, the browser must be told
+to always revalidate cached files using conditional requests. The correct
+semantics are achieved via the (confusingly named) `Cache-Control: no-cache`
+header that needs to be provided in the web server responses.
 
-It is possible to perform this conversion ahead of time, avoiding the extra
-load times. To do this please follow these steps:
+### Example Server Configurations
 
- 1. Install Node.js
- 2. Run `npm install` in the noVNC directory
- 3. Run `./utils/use_require.js --with-app --as commonjs`
+Apache:
 
-This will produce a `build/` directory that includes everything needed to run
-the noVNC application.

+    LoadModule headers_module modules/mod_headers.so

+noVNC is written using ECMAScript 6 modules. This is not supported by older

 Fortunately noVNC includes a script to handle this conversion. Please follow
 the following steps:
 
  1. Install Node.js
  2. Run `npm install` in the noVNC directory
- 3. Run `./utils/use_require.js --as <module format>`
