Hi Yutaka, I installed DeleGate 9.2.3-pre8 under Windows and Linux. The filtered web pages are shown quicker, quite very interesting !! I detect some few bugs (?), one major and two minors : - Under Windows and Linux, when I activate filter (FTOCL=myfilter.cfi), I have empty web pages for www.google.com or fr.yahoo.com. It seems that, for those particular web sites, there's empty input dataflow for filtering. Have you got any idea to resolve the problem ? - Under Windows, delegate create C:\var\spool\log\0 file even if I specified a DGROOT=C:\delegate - Under linux, for each page access, I have two lines Xfwrite in the shell console (not in the log) like : [8478] Xfwrite(1,19)=0, ferror()=1, errno=9 [8478] Xfwrite(1,274)=0, ferror()=1, errno=9 If you have a correction for the empty google page, it would be great.
