I try Helicon Jet on IIS6.0 and when enabled compression on dynamic or static content I got abracadabra in browser. You can see it yourself on this link: http://www.odintsovo.org/test/

Software environment:

Windows 2003 32bit service pack 2
Helicon Jet Version 1.1.0.24
ISAPI_Rewrite 3.1.0.64
ASP.NET version 2.0.50727

Hello!

It is looks like 'Transfer-Encoding: chunked' header comes,
but there is no chunks in response body.

1. Make sure that any caches are turned off (HeliconJet cache, IIS cache).
2. What technology is used in your application? (classic asp, asp.net, ...)
3. What other third-party extensions installed on IIS?
4. Could you please show your HeliconJet & ISAPI_Rewrite configs.

Thanks.

1. I use cache all ASP files in memory. I must turn this option off to entire web-server to can use HeliconJet on one site?
2. Classic ASP
3. No extension
4. I try to switch off ISAPI_Rewrite, but take same result
Code:

#################################################
# HeliconJet Configuration file
# Version 1, 1, 0, 24


NotifyOrder=HIGH


MaxCacheSize=0
MinFileSize=512
MaxFileSize=0
FileCacheDirectory=g:\cache\
ProxyRequests=enable
AppendQuerystring=enable

[Defaults]

[URL:/test/]
Static Level:9    Cache
Dynamic Level:6



[Cache-Control]
mime    text/javascript    7 days after access    public
mime    text/css    7 days after access    public

Hi!

Could you please disable HeliconJet cache.
Just replace line

Code:
Static Level:9 Cache


on

Code:
Static Level:9


Restart the site application and make request.

Thanks.

Now the source is:
Code:
<%
  Response.Write "Hello world!"
  Response.Flush
  Response.Write "Hello world!"
%>


We remove Response.Flush and get normal result!

Helicon Jet does't allow use the Response.Flush directive?

Hello!

We haven't managed to reproduce this situation in our environment.
The way IIS6 works with Output buffers is something unpredictable.
If solution without Response.Flush is working for you, please use it.
If you want us to investigate it further, please send us your complete metabase in xml and a sample of asp script.

Thanks.
