Static Files

Static files (javascript/css/html) can be referenced and returned in the static directory:

    <img src="/static/captura2.png">

Especial Static Files

static/favicon.(jpg|png|ico)

If you put a static/favico.jpg or static/favico.png or static/favico.ico into your static folder, it will automatically become the favicon.

static/404.html

If you put an static/404.html into your static file, it will be used when a 404 error occurs.

static/500.html

If you put an static/500.html into your static file, it will be used when an internal error occurs.

Custom Error Pages

To return a custom error page, place the <error_code>.html in the static directory. Creating a 500.html into the static directory, for example, will return this page when a 500 error occurs.

Smart Cache

Dynamic caching may be used inside HTML by using smart_cache:

    <img src="smart-cache='file.png'">

Inline inclusion

It's also possible to generate inline inclusion with:

    <div>
        inline-include='static/teste3.html'
    </div>

Smart Cache in Rendered Text

Smart caching with rendered text can be done with private_cweb_smart_static_ref:

#include "CWebStudioOne.c"

CwebHttpResponse *main_sever(CwebHttpRequest *request ){

    const char *lang = "en";
    const char *text = "text exemple";
    CTextStackModule m = newCTextStackModule();
    struct CTextStack *s = newCTextStack(CTEXT_LINE_BREAKER, CTEXT_SEPARATOR);

    m.open_format(s,CTEXT_HTML,"lang=\"%s\"" ,lang);
        m.open(s,CTEXT_HEAD);

            char *fav_icon_link = cweb_smart_static_ref("favicon.ico");
            m.auto_close_format(s,CTEXT_LINK,"rel=\"shortcut icon\" href=\"%s\"" ,fav_icon_link);
            free(fav_icon_link);

        m.close(s,CTEXT_HEAD);
        m.open(s,CTEXT_BODY);

            char *img_link = cweb_smart_static_ref("my_image.png");
            m.auto_close_format(s,CTEXT_IMG,"src=\"%s\" width=\"200px\"" ,img_link);
            free(img_link);

        m.close(s,CTEXT_BODY);
    m.close(s,CTEXT_HTML);
    return cweb_send_rendered_CTextStack(s,200);

}

int main(int argc, char *argv[]){
    CwebServer server = newCwebSever(5000, main_sever);
    CwebServer_start(&server);
    return 0;
}

These examples demonstrate how to handle static files and use smart caching.
