Hi Arun,

Welcome to ASPNET newsgroup.
As for the writing multi-file to browser, do you mean writing multiple
file stream into asp.net page's response stream, like we provide file
downloading functionality? If so, I'm afraid this is not possible because
the HTTP response has its standard structure which force it should has a
definite content-type, for example "text/xml" , "text/html",
"application/msword"... So we could only contains single stream in each
response. Even though you can manually write multi file stream into the
asp.net's response stream and specify a ambigous content-type, the
clientside browser won't be able to correctly handle it. In addition, I'm
wondering what's your detailed requirement on this , I think we may try
looking for some other means to bypass it. If you have any other questions
or ideas, please feel free to post here. Thanks,

Regards,

Hi,

I want to show two images or more in the browser. That's what I meant by
multi-file.

I will give you an example. We would stored many (around 10000) images in
hard-disk.
For a particular HTTP request we may have to fetch multiple images(jpg,gif)
and display it in browser.

We don't want to keep these images in Virtual Directory.

Hope you understood our needs.

-Regards
Arun

| Thanks for your response Arun,
|
| For displaying multiple images in webbrowser, currently the only means is
| through the <img> html element, however, when we use <img> elements in
our
| web page, that dosn't means the page which contain the <img> tags will
| contain all the binary stream of all those referenced images. At runtime,
| the browser will action like follow:
|
| 1. Browser request the web page and retrieve all the html content of that
| page and rendering in browser.
|
| 2. when we meet a <img> tag, it will lookup the "src" link and make new
| request to the remote server to retrieve image.
|
| So, as for your scenario, I think you can consider the following means:
|
| 1. Make a custom HttpHandler which will help retrieve image stream from
| your server's hard disk and write response stream out. Of course, each
| request can output only a sincle image stream.
|
| 2. In your web page, you can use <img> tag to reference image stream
| through the httphandler's url (with different qureystring parameters
| according to the image you want to retrieve).
|
| Here is a tech article discussing on building such a httphandler in
asp.net
| 1.x:

| Hope helps. Thanks,
