I would like the output of bundles minified with the built-in JsMinify and CssMinify to have "cache forever" semantics so that browsers don't keep requesting them over and over. The resultant URLs are hashed based on the content so there's no sense in not using "cache forever" semantics on URLs like this.
Preferably, I would like to do this without having to write my own custom bundle transform. Can this be done? Either by manipulating settings on the Bundle, or by putting the right things in the web.config file?

We had a vue js code for one of the functionality which we have deployed in production in Production minimized form.
Now I have lost the actual code (Vue js project) so I only left with minimized files (app.js, manifest.js, vendor.js and app.css) because of this I am not able to make any changes for that functionality.
Is there any way to extract the code from production files in vue js project and modify some of the logic.
There is no right anwser for this. You can only try to "hack" some way into webpack minified files. You can do it in Chrome Dev Tools when inspecting the minified file, then click on "Pretty Print" brackets below to format your code in a regular manner, but still all your original source code variables, fnames etc. are changed.. Only if you know some specific values, for examples hard-coded strings you can orient your way around it, but its a long shot...
I'm not a developer/programmer. I'm just someone trying to use Gitit to take notes. I've got it to the point where it runs on Windows, but the math looks best using MathJax. I don't want to rely on a remote CDN to get the MathJax working (power cuts and internet disconnections are very frequent here). The author of the app mentions it can be setup in "4 lines of code" in Happstack:
mathjax-script: https://d3eoax9i5htok0.cloudfront.net/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML
# specifies the path to MathJax rendering script.
# You might want to use your own MathJax script to render formulas without
# Internet connection or if you want to use some special LaTeX packages.
# Note: path specified there cannot be an absolute path to a script on your hdd,
# instead you should run your (local if you wish) HTTP server which will
# serve the MathJax.js script. You can easily (in four lines of code) serve
# MathJax.js using http://happstack.com/docs/crashcourse/FileServing.html
# Do not forget the "http://" prefix (e.g. http://localhost:1234/MathJax.js)
The link to the tutorial is broken, so I'd be grateful for some assistance. Is there is any MathJax configuration I need to change, or simply extracting the files will do? I'll be writing lots of math in gitit. I'd prefer not to set up Apache etc. to serve MathJax. Gitit already uses Happstack, I'd prefer using that. Thanks!
EDIT: Just to be clear I'm not sure how to assign the port 1234 to serve this script
Ok I got MathJax working using portable Apache and the MathJax archive downloaded from docs.mathjax.org. The URL needs to be of the form (assuming you extracted the files into apache2/htdocs/MathJax):
http://localhost/MathJax/MathJax.js?config=TeX-AMS-MML_HTMLorMML
I wanted to keep this lightweight by reusing the same instance of Happstack as Gitit, but that seems beyond my skills/available time right now.
EDIT: Just found out that ghc will pack everything into one exe when building. So I doubt it is even possible to use the same Happstack instance, as the root directory of the server doesn't exist?
From the documentation, the static directory should work just fine:
On receiving a request, gitit always looks first in the static
directory (or in whatever directory is specified for static-dir in the
configuration file). If a file corresponding to the request is found
there, it is served immediately. If the file is not found in static,
gitit next looks in the static subdirectory of gitit's data file
($CABALDIR/share/gitit-x.y.z/data). This is where default css, images,
and javascripts are stored. If the file is not found there either,
gitit treats the request as a request for a wiki page or wiki command.
So, you can throw anything you want to be served statically (for
example, a robots.txt file or favicon.ico) in the static directory.
You can override any of gitit's default css, javascript, or image
files by putting a file with the same relative path in static. Note
that gitit has a default robots.txt file that excludes all URLs
beginning with /_.

Download the MathJax.js file from e.g. cdn.mathjax.org and place it in data/static/js/MathJax.js. Then change the config you quote to:
mathjax-script: http://localhost:5001/js/MathJax.js
I'm trying to move from Classic to Super dev mode and seeing a problem in the latter. The problem is two-fold. First, it is trying to use the code server to give the css files to the web page. Here is a line from the element in the resultant web page:
<link rel="stylesheet" href="http://127.0.0.1:9876/tdome/../resources/standard.css">
You can see that it is piping the reference through the code server, which is running on port 9876. Now, that wouldn't be a big deal if it would serve the file. But it won't. The styles in that file are missing in the resultant page. This URL straight to the code server:
http://127.0.0.1:9876/resources/standard.css
... gives "server error". Eclipse is tossing a null pointer exception. It seems to have heartburn with files that are not in the /tdome tree. Just snuffling around and pecking in the names of existing files, sometimes Eclipse says it is ignoring the request. Sometimes it says the file doesn't exist when it does, and sometimes (when it really matters, like here), it gives the nullPointerException. At WebServer.java:272, fwiw.
So I need to either get superdevmode to leave these references alone, or get it to serve the file.
Any ideas? Many thanks-
Well, I really didn't find a way to make Super Dev Mode serve the files where they are. But I figured out where they should be instead of where they are. Probably common knowledge to everybody else: make a 'public' directory next to the 'your-project.gwt.xml' file and put them there. The references to them are in that xml file and do not need any qualification- just the filename, no directory path. Super Dev Mode will package them up, serve them, and let you at them.
Say you have a css files loader style.php:
<?php
header('Content-type: text/css');
foreach(array('style1.css', 'style2.css', 'style3.css') as $f)
echo file_get_contents($f)
?>
Style1.css has 12KB, style2.css is 400kgs, and in the red corner obese style3.css weighting 800LBs is world champion at static resource bandwidth consumption!
I'm using style.php to combine the three files and send them to the client. I'm also using similar php files to send out JS resources, combined.
Is there some htaccess rule that I can tell to combine several static resources into a big one, and send that on-the-fly?
/EDIT:
This type of job CAN be handled by htaccess I'm sure I've read somewhere about server files included or something like that but I don't remember where. And I've also seen free hosting services that put a custom header or banner regardless of what files you host there.
Well this type of job (combining css files) cannot be handled by .htaccess. You can at best use mod_deflate to compress the css file's contents.
However in PHP code you can combine and compress various CSS files. Take a look at third method in http://www.catswhocode.com/blog/3-ways-to-compress-css-files-using-php
Finally take a look at minify here: http://www.minifycss.com/minify-tools/minify-css-tools.php
Eventually found what I was looking for. The thing was called Server-Side Includes (SSI).
So I'm new to XUL.
As a language it seems easy enough and I'm already pretty handy at javascript, but the thing I can't wrap my mind around is the way you access resources from manifest files or from xul files. So I did the 'Getting started with XULRunner' tutorial... https://developer.mozilla.org/en/getting_started_with_xulrunner
and I'm more confused than ever... so I'm hoping someone can set me straight.
Here is why... (you may want to open the tutorial for this).
The manifest file, the prefs.js and the xul file all refer to a package called 'myapp', that if everything I've read thus far on MDN can be trusted means that inside the chrome directory there must be either a jar file or directory called myapp, but there is neither. The root directory of the whole app is called myapp, but I called mine something completely different and it still worked.
When I placed the content folder, inside another folder called 'foo', and changed all references to 'myapp' to 'foo', thus I thought creating a 'foo' package, a popup informed me that it couldn't find 'chrome://foo/content/main.xul', though that's exactly where it was.
Also in the xul file it links to a stylesheet inside 'chrome://global/skin/' which doesn't exist. Yet something is overriding any inline styling I try to do to the button. And when I create a css file and point the url to it, the program doesn't even run.
Can someone please explain what strange magic is going on here... I'm very confused.
When you register a content folder in a chrome.manifest you must use the following format:
content packagename uri/to/files/ [flags]
The uri/to/files/ may be absolute or relative to the location of the manifest. That is, it doesn't matter what the name of the containing folder is relative to your package name; the point is to tell chrome how to resolve URIs of the following form:
chrome://packagename/content/...
The packagename simply creates a mapping to the location of the files on disk (wherever that may be).
The chrome protocol defines a logical package structure, it simply maps one URL to another. The structure on disk might be entirely different and the files might not even be located on disk. When the protocol handler encounters an address like chrome://foo/content/main.xul it checks: "Do we have a manifest entry somewhere that defines the content mapping for package foo?" And if it then finds content foobar file:///something/ - it doesn't care whether that URL refers to a file, it simply resolves main.xul relatively to file:///something/ which results in file:///something/main.xul. So file:///something/browser.xul will be the URL from which the data will be read in the end - but you could also map a chrome package to another chrome URL, a jar URL or something else (theoretically you could even use http but that is forbidden for security reasons).
If you look into the Firefox/XULRunner directory you will see another chrome.manifest there (in Firefox 4/5 it is located inside omni.jar file). That's where the mappings for global package are defined for example.
