HttpCompress

Google code block me, why you host this project else where like SF.Net that is greater? google code is not realy open! becuase of political functions.

hi
is there any known bug in this module related to ajax?
i want to use this http module with asp.net ajax and i want to know is there any problem or not?

May I have the source code of version 7? I want to apply the code from issue 15 from google code.

I have configured this according to “http://www.c-sharpcorner.com/UploadFile/Ihelpable/httpcompression05022006094806AM/httpcompression.aspx?ArticleID=b0c4a586-97b4-4fbd-a95a-8b1200f0e068”. I tested compression using “http://www.whatsmyip.org/http_compression/” before and after configuring and it shows to be working. My client is running Windows XP. The site comes up fine after compressing on Firefox and Chrome, but IE7 cannot display the site. Adding a single aspx page to the exception list allows IE7 to display that page. Any suggestions on getting the site to display in IE7?

I’ve got this installed on IIS 6.0 and it appears to be working well. Thanks for providing.

I noticed, however, that the compression is not as good as IIS for some files. I was able to get IIS to compress EVERYTHING by editing the metabase and it compressed my file from 146k to 10k. With HttpCompressionModule, that same file is stuck at 22k.

Any idea why?

Sorry, a few other points and correction. We are running .NET Framework 1.1 and here’s our web.config with the tags changed so that the contents can be viewed:

[configuration]
[configSections]
[sectionGroup name=”blowery.web”]
[section name=”httpCompress” type=”blowery.Web.HttpCompress.SectionHandler, blowery.Web.HttpCompress” /]
[/sectionGroup]
[/configSections]

You surely mean “I’m now” :)

I noticed the same problem as mogadanez: httpCompress will compress static files when run in the Visual Studio Web Developement Server, but not in IIS6 with wildcard mapping set. It does however compress all dynamic requests as expected, including all my extension-less URLs, so the wildcard mapping actually seems to work.

Anybody any idea on what could be wrong here or how to work around it?

I understand it could become too CPU intensive for high-traffic sites to compress a lot of static content on the files (without server-side caching of compressed content as IIS could do it itself), but that’s not an issue for me now.

for those having issues with js files (and other static files) I found adding this:

To the HTTPHandlers node in web.config seems to work, no idea why as surely thats what its doing by default but there you go.

No. You would need a dedicated server. I looked into doing something just as CPU intensive a while back and I kept reaching my limits. I had to move it to a dedicated server which was about $180/month. Good luck!

I tried using this on a website running .NET 4 and I keep getting the error below. Any ideas?

Exception information:
Exception type: ArgumentOutOfRangeException
Exception message: Index and count must refer to a location within the string.
Parameter name: count
at System.String.RemoveInternal(Int32 startIndex, Int32 count)
at System.String.Remove(Int32 startIndex, Int32 count)
at blowery.Web.HttpCompress.HttpModule.CompressContent(Object sender, EventArgs e)

I use this dll for compression .It’s working fine. But when i export a report in world/Excel it’s showing this error

“Server cannot append header after HTTP headers have been sent. ”

My Code :

public static void ExportToWord(GridView gvReport,Panel tdReportInfo,string reportName)
{
try
{
reportName = reportName + “.doc”;
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.AddHeader(“content-disposition”,
“attachment;filename=” + reportName + “”);
HttpContext.Current.Response.Charset = “”;
HttpContext.Current.Response.ContentType = “application/vnd.ms-word “;
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
tdReportInfo.RenderControl(hw);
gvReport.RenderControl(hw);
HttpContext.Current.Response.Output.Write(sw.ToString());
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
}
catch (Exception ex)
{
ReallySimpleLog.WriteLog(ex);

}
}

Any suggestion please ?
