WTF::String -> String.

There's no need to use the WTF namespace for String.  There's a using
WTF::String directive in the header.

+
 // This class is used to serialize a page contents back to text (typically HTML).
 // It serializes all the page frames and retrieves resources such as images and CSS stylesheets.
 class PageSerializer {
 public:
-    explicit PageSerializer(Vector<SerializedResource>*);
+    explicit PageSerializer(Vector<SerializedResource>*, HashMap<WTF::String, WTF::String>* = 0, WTF::String = "");

Why not use the LinkLocalPathMap type here?

No need for the explicit keyword anymore.  That only does something for
one-argument constructors.

 
     // Initiates the serialization of the frame's page. All serialized content and retrieved
     // resources are added to the Vector passed to the constructor. The first resource in that
     // vector is the top frame serialized content.
     void serialize(Page*);
 
     KURL urlForBlankFrame(Frame*);
 
 private:
     void serializeFrame(Frame*);
 
     // Serializes the stylesheet back to text and adds it to the resources if URL is not-empty.
     // It also adds any resources included in that stylesheet (including any imported stylesheets and their own resources).
