Great, but it would be nice to have a tool that do all these compressions automatically.
I mean, you just upload the css/html/js files on the server without compression. On each client request on these files, the compression will be automatically done and then stored in a temp file. The next time a file will be requested, the tool will redirect the request to the corresponding temp file. Of course the temp file would be regenerated if its date is older than the date of original file.

Mathmax... Why would you want to do that? To prevent that the compression happens on every request? Because if that's what you mean, then I'm pretty sure that Mads took care of this by caching the compressed version of each file on the server. Changing the original files would then invalidate the cached version causing the compression to happen again.
Am I correct?

No TweeZz you are not correct
I had a look at the file now ;)

These are only some helper methods which can be used in HttpModules / HttpHandlers.
Mads has a bunch of them blog.madskristensen.dk/.../...nd-HttpHandlers.aspx

Hi Mads,

thank you for the seminar - excellent stuff! And thank you for sharing the optimizer-class, I'm looking forward to implementing it on a larger site, I'm maintaining atm. I'm off hunting those 0 KB..

Hope to participate in the next geek-dinner.

Mvh. Frederik

@Mads: thanks again for sharing - all your small posts (and the greater ones too - ofcourse ) really motivates to fire up VS now and then just to try some new idea your post triggered. Invaluable!

Now to the contents of this post - or rather the contents of the attachment. Wouldn't this line (#84):

body = body.Replace("\t", string.Empty);

in the method RemoveWhitespaceFromCss(...) possibly generate an error? What if a style is described as:

#someid p {.........}

where the whitespace between someid and p is a tab.

Hi Mads

Thanks a lot for the seminar.

Could you please include the code, that concatenated several css files into one ?

TweeZz, as you say these are only helper method. I would like to have an automatic tool that made compressions when files are requested?

Hi Mads

Thanks for the link.

Would it be possible to get a copy of the project you showed at the seminar ?

I am having problems, getting whitespace stripping and compression to work at the same time.

@Mads

No I didn't move back to Belgium Actually I never know which flag to choose. I definitely still feel more Belgian then Slovak, but I'm hardly ever there. Tough decision!

@mathmax

In the link I posted there are several handlers / modules that do what you're asking for. Here are the ones you might want to have a look at.
- compress webresources: blog.madskristensen.dk/.../...ceaxd-in-ASPNET.aspx
- compress webresources and aspx pages: blog.madskristensen.dk/.../...pages-in-ASPNET.aspx
- remove white spaces in aspx pages: blog.madskristensen.dk/.../...e-for-ASPNET-20.aspx
- combine css files (reduces the amount or requests): blog.madskristensen.dk/.../...eets-at-runtime.aspx
- 'minify' css files: blog.madskristensen.dk/.../...3525-at-runtime.aspx
- minify css and js files: blog.madskristensen.dk/.../...avaScript-files.aspx

I'm using a combination of all those techniques in our asp.net projects.
Great stuff! Njummie..

Hi @Mads,

I tried your code for compressing page output using GZip. I have added your code on page load of my web page,

HttpContext context = HttpContext.Current;
context.Response.Filter = new GZipStream(context.Response.Filter, CompressionMode.Compress);
HttpContext.Current.Response.AppendHeader("Content-encoding", "gzip");
HttpContext.Current.Response.Cache.VaryByHeaders["Accept-encoding"] = true;


But Its only compressing the .aspx file not the other external css & js files and images. Please tell me how can I compress my js, css and image files using code (becuase I am on shared hosting server and don't have access to IIS settings) in asp.net

Thanks,
