Examples with Resource org.apache.tapestry5.commons.Resource used on opensource projects

Example 1 with Resource

use of org.apache.tapestry5.commons.Resource in project tapestry-5 by apache.

the class ResourceStreamerImpl method streamResource.

public boolean streamResource(Resource resource, StreamableResource streamable, String providedChecksum, Set<Options> options) throws IOException {
    assert streamable != null;
    assert providedChecksum != null;
    assert options != null;
    String actualChecksum = streamable.getChecksum();

    // Even when sending a 304, we want the ETag associated with the request.
    // In most cases (except JavaScript modules), the checksum is also embedded into the URL.
    // However, E-Tags are also useful for enabling caching inside intermediate servers, CDNs, etc.
    response.setHeader("ETag", token);
    // If the client can send the correct ETag token, then its cache already contains the correct
    // content.
    String providedToken = request.getHeader("If-None-Match");

    if (productionMode && !options.contains(Options.OMIT_EXPIRATION)) {
        // Starting in 5.4, this is a lot less necessary; any change to a Resource will result
        // in a new asset URL with the changed checksum incorporated into the URL.
        response.setDateHeader("Expires", lastModified + InternalConstants.TEN_YEARS);
    }
    // mostly result in quick SC_NOT_MODIFIED responses.
    if (options.contains(Options.OMIT_EXPIRATION)) {
        response.setHeader("Cache-Control", omitExpirationCacheControlHeader);
    }
    if (streamable.getCompression() == CompressionStatus.COMPRESSED) {
