  Hi:
  
  Well this is difficult to believe at least in my experience dealing with Apache, PostNuke and Web pages. I have a directory that I erased from the web server. I stops the server and restart it and when I try to access the web dir it shows something (with error) but it should show a 404!
  
  My _mayor_ problem is the index page of my web site is loading twice. You will see the large white space after the page ends:
  
  http://www.politicaboricua.com
  
  However when you access a 'channel' it shows properly...
  http://www.politicab….com/Politica.phtml
  
  The haunted part is this:
  The directory named /usr/local/apache2/htdocs2/testbed WAS erased and it is reported as such by bash. But if I try to access:
  http://www.politicab…/testbed/News.phtml
  
  It SHOWS something... (when it should show a 404) I have stop and restarted the web server twice (I think I even rebooted) and it continues to show...
  
  My setup is Apache 2.2.2, PHP 5.1.4, PostNUke .762, MySQL 4.1.19.
  
  I **HAVE** erased all PostNuke related caches (pnRender_compile, AutoTheme _compile, pzLib) have stop and restart the server and this continues. Unless it is 'cache' installed by my ISP.
  
  Could someone confirm
  http://www.politicaboricua.com/testbed/News.phtml show a 404???
  
  Otherwise Apache 2.2.2 *might* have a cache thats is producing this..
  
  Please advise or comment... I really don't believe this is happennng... particulary for the 'double page' loading at index page. It is nasty.
  
  Later
  
  
  
  p.d.
  I am running PostNuke since august 2003, I am used to configure Apache, PHP and MySQL so please note that I am not a newbie regarding Web Technologies altough aI am not a programmer perse..

  Hi:
  
  Further researching shows this:
  
  Summary: mod_mem_cache crashes after requesting the same object
  twice
  Product: Apache httpd-2
  Version: 2.2.2
  Platform: PC
  OS/Version: Linux
  Status: NEW
  Severity: critical
  Priority: P2
  Component: mod_cache
  AssignedTo: bugs[at]httpd.apache.org
  ReportedBy: croller[at]generali.fr
  
  
  When requesting the same object twice (a cachable object that respond to the mem
  cache parameters), a segmentation fault is generated (ie. [Tue May 23 12:59:31
  2006] [notice] child pid 960 exit signal Segmentation fault (11)) with Apache
  2.2.2 on RHEL ES 3 (Linux apache 2.4.21-40.ELsmp #1 SMP Thu Feb 2 22:22:39 EST)
  acting as a reverse proxy, with both mem cache and disk cache enabled for
  several virtual hosts.
  
  Several things were tried, but it makes no difference:
  - reload or restart Apache
  - reboot
  - disabling disk cache
  - changing mem cache parameters
  - request with "deflatable" and "not deflatable" objects
  - request with different browser (Firefox 1.5.0.3, IE 6.0SP2, telnet...)
  - requesting different objects (but still 2 times following) on different
  virtual hosts
  
  But disabling mem cache always makes it work perfectly without crashes.
  
  This is an exemple of telnet request (extracted from tcpdump):
  GET /fichiers/1417/00000012.htm HTTP/1.1
  Accept: */*
  Referer: http://www.my-site.com/synergies/Pages/index_FS.asp?res=1024&
  Accept-Language: en-us
  User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)
  Host: www.my-site.com
  Connection: Keep-Alive
  
  This is the cache configuration:
  CacheDefaultExpire 60
  CacheLastModifiedFactor 0.1
  CacheMaxExpire 86400
  
  CacheEnable mem /
  MCacheMaxObjectCount 10000
  MCacheMaxObjectSize 32768
  MCacheMaxStreamingBuffer 16384
  MCacheMinObjectSize 0
  MCacheRemovalAlgorithm GDSF
  MCacheSize 32768
  
  
  CacheEnable disk /
  CacheDirLength 2
  CacheDirLevels 3
  CacheMaxFileSize 1000000
  CacheMinFileSize 64
  CacheRoot /var/cache/apache
  
  This *might* be also related:
  http://issues.apache…ow_bug.cgi?id=39647
  
  This was posted on may 23, 206. So I guess it is related with my problem. Problem is Apache release builds at 3-4 months intervals... Unless I risk trying cvs code once a fix is applied to the three...

  Hi:
  
  Well, I think that the problem with the erased dir and the web page showing is related with _short urls_ since any word I wrote besides htdocs produces a similar output. So the web page is NOT haunted!
  
  BUT.......... still have to fix the double index page loading.
