Re: [users@httpd] result codes from Bash CGI

[Claude Warren]

Is there documentation for any of these methods?  If you can point me to
the proper section of the code base I can probably figure it out and
document if necessary.

[users@httpd] mod_proxy and ProxyErrorOverride Directive

[Sean LeBlanc]

We have switched from mod_jk to mod_proxy_ajp recently, and I'm trying 
to get similar behavior to what we did via uriworkermap.properties 
files, in which we blocked most error codes coming from our Java 
application, for example:



/app|/*worker1;use_server_errors=401, serve up instead>



It seems one way of achieving similar things via mod_proxy/mod_proxy_ajp 
would be to use:



"ProxyErrorOverride On"


That then blocks most of what we want, however, it blocks too much. We 
want a few error codes to be served up by our Java application instead 
of Apache. Is there a way to do this?

RE: [users@httpd] stickysession and BalancerMember route

[DICKEY Rob]

Thanks - I found that 64 limit in code, and did not look like any other 
character in the route string match would be problematic but for a route value 
like route=ab-8080-cde1 we are finding that stickiness is not consistent... the 
preamble to the route is another string like WebAppName.ab-8080-cde1 but in all 
cases the separator character is present...and the client is being sent and 
presenting the stickiness cookie as expected.

When we modify the route to be simple like route=a80801 the stickiness works as 
expected.

I'll keep debugging.

Thanks.

Rob

The route is limited to 64 characters and must be preceded by a special 
character within the URL/cookie value (default character is '.', though 
stickysessionsep= might be used to change it). These are the only constraints 
I'm aware of..

But this means that the backend must set routed URLs/cookies of that form, 
otherwise some "automatic" routing can be performed like in 
https://httpd.apache.org/docs/2.4/en/mod/mod_proxy_balancer.html#example
(the one using mod_headers).
