If custom subdirectory is configured with config.absRefPrefix, fullUrl returns wrong absolute uri

If config.absRefPrefix is used, fullUrl returns wrong absolute uri

Reported by @Teddytrombone via PR #353 :

Example:
config.absRefPrefix = /test/
results in http://example.com/test/test/page/ instead of http://example.com/test/page

PR #353 should work with sites which use config.absRefPrefix as well as config.baseUrl

MetaSEO version: 2.0.3

TYPO3 version: 7.6.15

@Teddytrombone Thanks for catching and patching this. I have some questions:

• Which versions are you using?
• Which is the URL of your root page (e.g. http://www.example.com/test/)?

[thomaszbz]

If this can be classified as a bug, then it's (very likely) a regression via d8b91f6 which went productive via 1.0.6. Affected versions are 1.0.6 - 2.0.3, respectively (issue #355).

When reviewing the fix provided by @Teddytrombone, we need to make sure to not introduce the // problem again (issue #355). Eventually, add this to the test suite.

Which versions are you using?

We are using the current version from TER (2.0.3)

Which is the URL of your root page

I don't know, if get the question right. Do you mean the TYPO3 frontend? On our development server, we have TYPO3 installations in subdirectories, but needed the config.absRefPrefix (to get over some inline svg limitations in Firefox). So our configuration is:
config.absRefPrefix = /subdirectory/
The TYPO3 frontend is accessible via http://internal.domain/subdirectory/ and the backend via http://internal.domain/subdirectory/typo3/

With the above configuration, all internal links are absolute links (of course), but for example for the canonical url the subdirectory is duplicated, for example the root page: http://internal.domain/subdirectory/subdirectory/

Or a subpage http://internal.domain/subdirectory/de/some/test/page/ gets the canonical url http://internal.domain/subdirectory/subdirectory/de/some/test/page/

The cause is, that in GeneralUtility::fullUrl always TYPO3_SITE_URL is prepended, which returns the domain and the subdirectory. So for absolute links, only the domain should be prepended.

I hope, this clarifies things ;-)

[thomaszbz]

The TYPO3 frontend is accessible via http://internal.domain/subdirectory/

That answers it.

Which TYPO3 version are you using?

[Teddytrombone]

Which TYPO3 version are you using?

TYPO3 7.6.15

[thomaszbz]

With minimal configuration:

config.tx_realurl_enable = 1
config.absRefPrefix = /customdir/

Reproduced for sitemap index:

However, URLs in a sitemap page are correct:

Part of the problem is that we call fullUrl() with both, absRefPrefixed and unprefixed paths.

@Teddytrombone @MichiBeck, @pdanzinger, @bla-kw, @fdrewes Could you please test/review patch 70d84d6 against your test environments?

I don't want to introduce another regression here. It's a #357-similar issue, just with absRefPrefix = /customdir/, meaning that TYPO3 is installed in a subdirectory.

For your root page, eventually you have to work around a RealUrl issue. See #370.
