        // Next get should return the same instance from cache
        byte[] reused = impl.getBuffer();
        assertSame(b, reused, "Buffer should be reused from cache");
        // And it should still be zeroed
        for (byte value : reused) {

    }

Since HTTP requests frequently happen in parallel, connection pooling must be thread-safe.

These are the primary classes involved with establishing, sharing, and terminating connections:

                            log.debug("Cannot reuse, signing enforced on connection " + conn);
                        }
                        continue;
                    }

                    if (!conn.getNegotiateResponse().canReuse(tc, forceSigning)) {
                        if (log.isTraceEnabled()) {
                            log.trace("Cannot reuse, different config " + conn);
                        }

from starlette.exceptions import HTTPException as StarletteHTTPException
```

### Reuse **FastAPI**'s exception handlers { #reuse-fastapis-exception-handlers }

If you want to use the exception along with the same default exception handlers from  **FastAPI**, you can import and reuse the default exception handlers from `fastapi.exception_handlers`:

{* ../../docs_src/handling_errors/tutorial006.py hl[2:5,15,21] *}

 * Fix: Persist proper `Content-Encoding` header to cache for GZip responses.
 * Fix: Eliminate rare race condition in SPDY streams that would prevent connection reuse.
 * Fix: Change HTTP date formats to UTC to conform to RFC2616 section 3.3.
 * Fix: Support SPDY header blocks with trailing bytes.
 * Fix: Allow `;` as separator for `Cache-Control` header.

        assertFalse(pool.contains(nonPooled), "Non-pooled connection should not be tracked");
    }

    @Test
    @DisplayName("Should create new connections when reuse conditions are not met")
    void testNoConnectionReuse() throws Exception {
        // Given: Create a new pool for this test to ensure isolation
        SmbTransportPoolImpl testPool = new SmbTransportPoolImpl();

	return res
}

// metaCacheEntriesSorted contains metacache entries that are sorted.
