Response to: GZIP memory leak and content length problems
Hi Krem, I am working on compressing the content using GZIPOutputStream.On my local machine everything is working fine. Using struts on weblogic 8.1. But when I try to get that page from another machine pointing my local server, I am getting a FileDownload dialog and if I open it, there is binary content. Could you please suggest anything on this. Thanks, sai

  After 3 days analysis on Weblogic 8.1 i have found the solution for this problem. If guys need the solution contact me at chinu_en@yahoo.com. Since i really need to know how many have come across this situation.

  solution :
  1. Dont try to compress html files from weblogic 8 (not tried with any other weblogic version).
  2. Dont give multiple route of mapping to a filter in web.xml in weblogic 8.
  
  To be more clear on second point ,
  
  <filter-mapping>
  <filter-name>CompressionFilter</filter-name>
  <url-pattern>/servlet</url-pattern>
  </filter-mapping>
  
  <filter-mapping>
  <filter-name>CompressionFilter</filter-name>
  <servlet-name>Index</servlet-name>
  </filter-mapping>
  
  <servlet-mapping>
  <servlet-name>Index</servlet-name>
  <url-pattern>/servlet</url-pattern>
  </servlet-mapping>
  
  All the request has a url patern "/servlet" passes through CompressionFilter.
  All the request will reach the Index Servlet will also passes through CompressionFilter.
  If a request matches both the above condition then response will be compressed twice.
  Thus creates the prob of FileDownload dialog or junk chars shown.
  This will not happen in tomcat.
