When asp.net page loaded in to browser there are lots of white spaces between tags and in tags that will increase your html kb. For example if your page around 300 kb then it will take 3 second to load on 100 kbps internet connection and in dial up connection it will still take time. So if you want to load your site fast on dial up internet connection then you need to decrease html kb as much you can and removing white spaces from the html will be good idea for that.
Following is the code for the page on which you want to remove white spaces from the html. It will decrease your html kb by 30 percentage.
private static readonly Regex REGEX_FOR_TAGS = new Regex(@">s+<", RegexOptions.Compiled);
private static readonly Regex REGEX_FOR_BREAKS = new Regex(@">[\s]*<",
RegexOptions.Compiled);
protected override void Render(HtmlTextWriter writer)
{ using (HtmlTextWriter writer = new HtmlTextWriter(new System.IO.StringWriter()))
{ base.Render(writer);
string htmlkb = writer.InnerWriter.ToString();
htmlkb = REGEX_FOR_TAGS.Replace(htmlkb, "> <");
htmlkb= REGEX_FOR_BREAKS .Replace(htmlkb, "><");
writer.Write(html.Trim());
}
}
Here in the above code there are two regular expression one for white space in tag and another for whitespace between tag and by just overriding the render event of event you can replace the whitespace.
Happy Coding...
