Where does Shibboleth SP cache target URLs?

[Jose Hales-Garcia]

Hello,

I’m trying to understand where a target’s URL is cached in an Apache/Shibboleth SP system.

Many of our target URLs contain long query strings exceeding 80 bytes (the limit of RelayState).  Yet Apache/Shibboleth passes these long target URLs in tact on successful authentication.

Is caching a target URL something Apache does, or Shibboleth SP?

Thank you,
Jose
