New Revision: 549857
URL: http://svn.apache.org/viewvc?view=rev&rev=549857
Log:
Update jk_canonenc and add it to IIS and Netscape.
- Remove unnecessary parts from the Apache reencoding port.
Those parts will become outdated and keeping them in the source
suggests they are well maintained.
Streamline jk_canonenc, in contrary to it's httpd origins,
we only use it in the reverse proxy case.
- Change the contract for jk_canonenc to make it better suited to
be used by all web servers:
- the length parameter now gives the maximum length to use
for the encoded URL
- the original URL needs to be '\0'-terminated.
- We now set a return value, indicating if the new URL got to large
- Add proxy encoding to IIS (new default)
and netscape (no choice).
- Add jk_url to the IIS build files
- Add forwarding debug logging to IIS and Netscape,
to make checking the URL reencoding easier.
