OIDC SSO lose Query parameter of original page

[T-Doschke]

Introduction

Sqlpage adress called with Query parameters ...page.sql?Param=1
OIDC is configured with microsoft Azure EntraID
Browser will be redirected to Microsoft OIDC page, authorization is fine, cookie will be set and as last step browser will be redirected to ...page.sql without the original ?Param=1 part.

To Reproduce

using SQLpage v0.35.2 in combination with OIDC SSO and having cookies deleted in Browser.
Browse to a sqlpage.sql?param=1 webseite,
All the OIDC stuff is working perfect but the last redirect back is only to sqlpage.sql without the original query param=1 part.

Can't test, but i think is is true for other OIDC providers too.
Have not tested if its the same for Post Parameters.

Expected behavior

the question is, is it possible to have the last redirect back to the sqlpage page with the original query parameters?
is there any other solution for combining OIDC login and parameters for an sqlpage page?

Version information

• OS: Windows Server 2025
• Database MS SQL 2022 enterprise
• SQLPage Version v0.35.2
• OIDC SSO with Microsoft Azure EntraID
  Configuration is with ARR and URL Rewrite to handle multiple SQLPages instances on different Ports and URL Parts on same Host, but the issue is same in "native" mode, so it has nothing to do with ARR and URLRewrite.

this issue is may be related to
https://github.com/sqlpage/SQLPage/blob/main/src/webserver/oidc.rs
Line 619
where only the original URL path is stored instead of URL path and query parameters.
but i have no real knowledge of that code.

And by the way Line 29 does not honor if configuration has a "site_prefix" set.
So the OIDC Callback is done always to "root" of webserver, not the prefixed sqlpage page.
