HTML pages in EE


When I ask a question I receive the following address in the address bar:

After submitting the question,  the Address in the Address bar becomes something like this:

This is a database driven website.  When I submit using askQuestion.jsp it goes to a database,  probably Oracle.  Then question becomes an .html page instead of

How is that done.  Submit a form using JSP then view the question in HTML,  also the question has a number.

Thank you

For each question, seperate HTML page must be generated..Otherwise I do not think google can search the questions ..

They might have configured their webserver to parse

into queryquestion.jsp?q=21221680

Or whatever.

Hi RJ,

Thank you for your reply.

Each form will generate an HTML page with question ID.  But,  when you reply to a subject,  you add to the HTML page,  how is this done?

The HTML page itself is divided into the asker name and the persons who reply.  How is that done.  Is it limited to JSP or it can be done via ASP and PHP?

Starting with Angular 5

Learn the essential features and functions of the popular JavaScript framework for building mobile, desktop and web applications.

It can also be done in ASP or PHP and there are a few ways to do it.  One way is to use the Apache mod_rewrite module.  Here's a tutorial that shows you how to do it:  More details can be found in Apache's URL Rewriting Guide (  Here's an IIS/ASP trick using IIS's custom error messages -  Another IIS option is to use an ISAPI filter like ISAPI Write (, which is closer to the Apache mod_rewrite solution.

<< I do not think google can search the questions >>
To clarify, Google and any other major search engine can crawl and index dynamic pages, but "it helps to keep the parameters short and the number of them small" (according the Google's Webmaster Guidelines -  What this means is that if you use something like, you're probably ok, whereas if you use something like .../question.jsp?category=web_development&asker=hhammash&other_stuff=very_important&more=info, you're looking for trouble.

On Apache servers at least (and probably others too), there is a method called 'Mod Rewrite' that allows you to parse static looking URLs into parameters. Thus you could have a page that, really, is mypage.php?year=2004&month=10&day=30 but is accessable as .../mypage/2004/10/30

A few pointers :

Apache's  Mod Rewrite :

Some alternatives for different server...:
 IIS ReWrite (
 ISAPI ReWrite (

Good luck :)
Just noticed that my Apache's URL Rewriting Guide link is for Apache 1.3 and PaulPosition's is Apache 2.0.  I think the document is the same, but you probably want to use the 2.0 one just in case (if you're using Apache 2.0 and go that route).

Thank you for your detailed replies,  I'll take a look at the tutorials.

There is still a part to my question.  When you reply to my post,  it adds to this HTML page.  Is it also by rewriting and giving an anchor to it?

The content of the page is dynamic.  When I submit this reply it will be added to the E-E database.  When you request this page, the E-E server will generate this page using the question id (21221680) to populate the page with your question and subsequent comments (including this one).

Each comment is given an anchor, ie. your last comment was #12686471 (hence, but that is only for identification/navigation purposes.  The page could be populated without the anchor.

The URL will then be rewritten from whatever its dynamic form is ie. .../question.jsp?qid=21221680 to it's current form .../Q_21221680.html using the mod_rewrite (I presume since E-E is hosted on Apache servers).
With the exception of a few static text pages, there are no HTML pages on the server.  All pages are generated from queries and page generation using jsp.  The tomcat app servers are just a collection of servlets, the apache parse and creates the arbitrary url.  It also decodes the links sent, because the only part that it needs to pass to the backend is the Q number.

Try this: the link for this question is:
put it in your address bar as:
it will still find it.  Is the page in multiple directories?  No it does not exist until the app server creates it, and the web server just adds the navigation as if they were directories.

This kind of setup is not at all unusual.  You will not find many modern large sites where they have a lot of static pages.  Almost everything today is generated on demand.

Thank you all for the answers.


Yes I've seen these pages even in ASP forums.

Yes the Javascript link worked.

Does this mean that this html page Q_21221680 does not exist?  Whenever we call it it gets generated?

"Does this mean that this html page Q_21221680 does not exist?  Whenever we call it it gets generated?"
Right, it doesn't exist on the server in this form, but when you use the simplified URL, it is able to interpret what you mean, create the page, and send it to you.

Nice procedure.

Final question:

- What is the purpose of generating HTML pages while we can simply have .jsp, .asp or .php?

Thank you
"Nice procedure."
Yes, very handy.

One reason touched on above is to make a URL more search engine friendly.  As noted, the major search engines can crawl and index dynamic page URL's up to a point.  Another reason is to simplify things for the website users.  I'm sure you've seen some wild and extremely long dynamic URL's on the web.  This process makes it much easier for us to use, remember, link to, and share these pages.  And in web development, ease of use is extremely important.
