    // forwarded to the login using a GET request BEFORE the first json POST request
    HttpCacheObject httpCacheObject = new HttpCacheObject(cacheKey, content);
    // Suppress automatic "compatibility mode" in IE in intranet zone

Example 2 with HttpClientInfo

use of org.eclipse.scout.rt.server.commons.servlet.HttpClientInfo in project scout.rt by eclipse.

the class BrowserFieldContentHttpResponseInterceptor method intercept.

@Override
public void intercept(HttpServletRequest req, HttpServletResponse resp) {
    ContentSecurityPolicy csp = BEANS.get(ContentSecurityPolicy.class).appendScriptSrc("'unsafe-inline'");
    // Bug in Chrome: CSP 'self' is not interpreted correctly in sandboxed iframes, see https://bugs.chromium.org/p/chromium/issues/detail?id=443444
    // Workaround: Add resolved URI to image and style CSP directive to allow loading of images and styles from same origin as nested iframe in browser field
    HttpClientInfo httpClientInfo = HttpClientInfo.get(req);
    if (httpClientInfo.isWebkit()) {
        String resolvedSelfUri = m_browserUri.toString();
        csp.appendImgSrc(resolvedSelfUri).appendStyleSrc(resolvedSelfUri);
    }
    String cspToken = csp.toToken();
    if (httpClientInfo.isMshtml()) {
        resp.setHeader(HttpServletControl.HTTP_HEADER_CSP_LEGACY, cspToken);
    } else {

    }
}

Example 3 with HttpClientInfo

use of org.eclipse.scout.rt.server.commons.servlet.HttpClientInfo in project scout.rt by eclipse.

the class UiSession method createUserAgent.

    JSONObject userAgent = jsonStartupReq.getUserAgent();
    if (userAgent != null) {
        // TODO [7.0] cgu: it would be great if UserAgent could be changed dynamically, to switch from mobile to tablet mode on the fly, should be done as event in JsonClientSession
        String uiDeviceTypeStr = userAgent.optString("deviceType", null);
        if (uiDeviceTypeStr != null) {
            userAgentBuilder.withUiDeviceType(UiDeviceType.createByIdentifier(uiDeviceTypeStr));
