JSP Sayfası İçinde Response Redirect

jsp:include tagi ile içeriğini aldığınız sayfa eğer Response redirect ile başka bir sayfaya yönlendirme içeriyorsa, browserınız o sayfaya yönlendirme yapmak yerine sayfaya aşağıdaki içeriği koyar:

URL moved here

Bunu engellemek için, bir sayfanın içeriğini almakta jsp:include tagini değil @include tagini kullanın.

Örnek:

<jsp:include page="icerik.jsp"/>
<%@include file="icerik.jsp"%>

Web Sayfasında Flashların En Üstte Görünmesini Engellemek

Geçenlerde içinde flash bulunan bir sayfa üzerine şeffaf bir layer koymaya çalışırken şöyle bir problem yaşadım. Sayfadaki flash objesi ne yaparsam yapayım layerın üzerine çıkıyordu.

Flashın bulunduğu yere "z-index:-1" vermem de bi işe yaramadı.

Bakınız:
You can't make a flash movie behave in the z-index - doesn't matter whether the movie is in a layer (div) or not it will always show up on top of any layers that overlap the movie.
Kaynak

Problemin çözümöü flashın "wmode" parametresini "transparent" yapmakmış.

Bakınız:

click on the flash file in dreamweaver... open up its parameters.. and make the

parameter: wmode
value: transparent
