Topic: Tweak the HTTP response from apache proxy server

[psd_mpl]

I have apache proxy server FrontEnd and BackEnd . In Apache BackEnd Server ,the proxypass URL is throwing connection timeout error that is Error Code 502/503 .The same error response is sent back to Front End .

Now I want to tweak the HTTP Status code in Apache Proxy Server BackEnd before sending it Apache Proxy Server FrontEnd.

The logic should be something like this

<Location "/">
ProxyPass "https://www.connectiontimeouturl.com/"
ProxyPassReverse "https://www.connectiontimeouturl.com/"
// just a logic
if(http_status from proxypass == 502 / 503)
{
tweak the response and then send it to apache FE
}
</Location>


Is there any other solution for this issue??

I just want to manipulate the HTTP status code before sending the response to FE.

Any other alternative solution will be appreciated

----

I have a apache proxy server setup in windows and linux.
The configuration of httpd.conf are same in both windows and linux .Here is the conf

<Location "/">
#adding Error document details
ErrorDocument 502 ${serverroot}/file.html
ErrorDocument 503 ${serverroot}/file.html
ProxyPass "https://someurl.com"
ProxyPassReverse "https://someurl.com"
</Location>

So whenever the proxypass throws the error 502/503 , it redirects it to error document i.e to the page file.html.

When I checked the access logs , found the difference in the response in windows and linux systems.

In windows --- > POST / HTTP/1.1" 302


In Linux ----- > POST / HTTP/1.1" 502

Why there is difference in response ??
Error code 302 is redirection code .Why windows is sending redirection error code but not linux ???
