Subject Re: [users@httpd] Any Comparisons? -- mod_wl vs mod_proxy vs mod_jk
Date Mon, 09 Feb 2015 10:28:20 GMT
Hello Nick (niq), ezra-s here.

I don't vouch for oracle documentation as inquestionable but I'll try to
explain the best I can in my experience.

WLSRequest on
* Lower overhead with WLSRequest on as opposed to SetHandler
weblogic-handler common method to handle when locations / extensions should
be proxied to weblogic backend.
* Documentroot on slow filesystem, as of nfs, I have experiened this.
 * Resolves 403 errors for URIs which cannot be mapped to the

For what I understand it means that filesystem is not checked with
WLSRequest, but it is when you use the common SetHandler weblogic-handler
method to make a specific location/file be proxied to weblogic server.

About "filesystem length restrictions" I also have seen this with requests
with a very long uri, we even have had some queries about this one in
#httpd. Not sure it 100% related, but when compiling apr "make test" will
report an error for this too, in ext4 at least, haven't checked others

Regards (don't punish me too much! ;P)
