I imagine you trying to remove these to satisfy some security / obfuscation requirement.

As far as the Splunkweb CherryPy header goes, that should be in the CherryPy python code somewhere. This is obviously editable by you in your own installation. However, you'll need to be incredibly careful to not break anything -- and this would be overwritten on upgrades.

For the Splunkd header itself, this is compiled into splunkd. I guess you could patch the binary with a hex editor, replacing the "Splunkd" characters with NULLs. This would be EXTREMELY RISKY and not at all recommended.

If this is important to you, I would recommend submitting and Enhancement Request with the details behind why this is needed and exactly what enhancement you are looking for.

removing or modifying the CherryPy header will affect the PDFserver ability to generate PDF. thus, you need to modify the PDFserver code at ../splunk/etc/apps/pdfserver/bin/pdfhandler.py

Comment out these 3 lines to not check for the existence of CherryPy header:

if 'CherryPy' not in response.get('server', ''):
logger.warn("Remote web server at %s doesn't appear to be running CherryPy" % version_url)
return False

the closet file that i can locate is: ..\splunk\lib\python2.6\site-packages\cherrypy_cprequest.py

is this the correct file?

which particular py file contains the Splunkweb CherryPy header ?
