Session breaks when i have multiple apache servers

[Sugavanam]

Hello
I have multiple apache server with multiple applications protected by path & proxy it to end application.
Example of code inside vhost:

Oidcredirecturi /redirect t_uri/
Oidcscope openid profile Oidcprovideruri Oidc clientsecret Oidcclientid
Oidccacchetype: file
Oidccachedir: /var/cache/oidc

<location /abc>
AuthType openid-connect
OIDCAuthRequestParams acr:i1
Oidcpathscope sgh
OidcUnautzaction auth
Require valid-user
ProxyPass https://example.com/abc
ProxyPassReverse https://example.com/abc

<location /xyz>
AuthType openid-connect
OIDCAuthRequestParams acr:i2
Oidcpthscope sgr
OidcUnAutzaction auth
Require valid-user
ProxyPass https://example.com/xyz
ProxyPassReverse https://example.com/xyz

This configuration is working fine when I use one apache server
But when I use this same configuration with multiple servers, the user session breaks
Can you please guide me on this issue?

I also read the stepup authentication document notes which states OpenID Connect Session Management does not work with per-path authn request params & scopes
https://github.com/OpenIDC/mod_auth_openidc/wiki/Step-up-Authentication

Iam using both authrequestparam & also scopes
Is there any alternative way to resolve this issue?

Apologies I was using server-Cache and it was not shared properly between multiple apache servers
