+<p>Transaction properties are accessed using the <xref href="GUID-2E673024-239B-3965-8880-C47B7CC24EF6.dita#GUID-2E673024-239B-3965-8880-C47B7CC24EF6/GUID-88CFB38B-9E3F-389A-B020-F2E62A09998F"><apiname>RHTTPTransaction::PropertySet()</apiname></xref> method,
+which returns an <xref href="GUID-C23D0EDB-E024-35AD-97E9-88FB6DC0EC7E.dita"><apiname>RHTTPTransactionPropertySet</apiname></xref> handle. They
+are used to store information related to a transaction that is required to
+persist during the transaction lifetime. Such information is not transmitted;
+the mechanism only provides an association, mainly used by Symbian developers
+for filter. </p>
+<p>The two pre-defined properties that can be set by the client are <xref href="GUID-7BB3CFA5-4697-305D-B4FD-D8747BB56E04.dita#GUID-7BB3CFA5-4697-305D-B4FD-D8747BB56E04/GUID-C9F345D9-C713-3C99-AFEE-1292D1EB61D9"><apiname>HTTP::EUsername</apiname></xref> and <xref href="GUID-7BB3CFA5-4697-305D-B4FD-D8747BB56E04.dita#GUID-7BB3CFA5-4697-305D-B4FD-D8747BB56E04/GUID-A803D500-6EED-35BE-B0CB-B01B2150B1CC"><apiname>HTTP::EPassword</apiname></xref>.
