Web Server Check Tool
Help Page

Copyright © 2016 Michael Talbot

## Overview

This utility allows you to perform a range of tests on web and DAV servers to check their functionality.

The currently supported checks are: HEAD, OPTIONS, PROPFIND, REPORT and SEARCH (in custom query only) and you can now specify your own custom query.

NB: Only HTTP and HTTPS protocols are supported and you MUST specify the protocol in the URL field.

## Notes:

1. Only "Basic" and "Digest" authentication are supported.
2. If you want to provide authentication then you must tick the "Enable Authentication" check box.
3. If you cancel a custom query the extension will perform an OPTIONS query instead.
4. The SEARCH query is only available as a custom query and the "Depth" option is ignored as the depth should be specified as part of the query.
5. SSL certificate errors are ignored unless they cause a connection failure. You can see the certificate details by clicking on the "View SSL Certificate" button.

## Known Issue:

- "Digest" authentication is experimental and sometimes fails.

## Synapse Network Library

The Synapse network library is available under a BSD-Style license and is used to provide the networking capabilities used in "Web Server Check Tool". Synapse uses OpenSSL to provide SSL and TLS support. I modified the following files to provide additional abilities that I required:

- blcksock.pas
- httpsend.pas
- ssl_openssl.pas

The modified Synapse files have been included and are released under the same license as the original files.

## OpenSSL Files

The following OpenSSL files have been included with the Windows version of the "Web Server Check Tool" as a courtesy and are released under the OpenSSL license as listed below.

- openssl.exe
- libssl32.dll
- libeay32.dll

For legal reasons IDEA, MDC2 and RC5 have not been compiled in to the version provided. If you wish to include support for them you will need to provide your own versions of the files.

If you do not want SSL/TLS support then you can delete the files. If you want to use your own versions replace the files with your preferred ones. The only files required are "libssl32.dll" and "libeay32.dll".

## Certificate Authority (CA) Certificates File

The "ca-bundle.crt" file contains the CA certificates for the OpenSSL libraries so that certificate information can be determined. It was generated using the "gen-ca-bundle.sh" script from cURL and uses the certificate store from Mozilla.

The "ca-bundle.crt" file is released under the same Mozilla Public License as the certificate store from Mozilla.

        Licensable by such Contributor to use, reproduce, make available,
        modify, display, perform, distribute, and otherwise exploit its
        Contributions, either on an unmodified basis, with Modifications, or

    become effective for each Contribution on the date the Contributor first
    distributes such Contribution.

    2.3. Limitations on Grant Scope

    The licenses granted in this Section 2 are the only rights granted under
    this License. No additional rights or licenses will be implied from the
    distribution or licensing of Covered Software under this License.
    Notwithstanding Section 2.1(b) above, no patent license is granted by a
    Contributor:

    (a) for any code that a Contributor has removed from Covered Software;
        or

    (b) for infringements caused by: (i) Your and any other third party's
        modifications of Covered Software, or (ii) the combination of its
        Contributions with other software (except as part of its Contributor
        Version); or

    (c) under Patent Claims infringed by Covered Software in the absence of
        its Contributions.

    This License does not grant any rights in the trademarks, service marks,
    or logos of any Contributor (except as may be necessary to comply with
    the notice requirements in Section 3.4).

    2.4. Subsequent Licenses

    No Contributor makes additional grants as a result of Your choice to
    distribute the Covered Software under a subsequent version of this
    License (see Section 10.2) or under the terms of a Secondary License (if
    permitted under the terms of Section 3.3).

    2.5. Representation

    Each Contributor represents that the Contributor believes its
    Contributions are its original creation(s) or it has sufficient rights
    to grant the rights to its Contributions conveyed by this License.

    2.6. Fair Use

    This License is not intended to limit any rights You have under
    applicable copyright doctrines of fair use, fair dealing, or other
    equivalents.

    2.7. Conditions

    Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
    in Section 2.1.

    3. Responsibilities
    -------------------

    3.1. Distribution of Source Form

    All distribution of Covered Software in Source Code Form, including any
    Modifications that You create or to which You contribute, must be under
    the terms of this License. You must inform recipients that the Source
    Code Form of the Covered Software is governed by the terms of this
    License, and how they can obtain a copy of this License. You may not
    attempt to alter or restrict the recipients' rights in the Source Code
    Form.

    3.2. Distribution of Executable Form

    If You distribute Covered Software in Executable Form then:

    (a) such Covered Software must also be made available in Source Code
        Form, as described in Section 3.1, and You must inform recipients of
        the Executable Form how they can obtain a copy of such Source Code
        Form by reasonable means in a timely manner, at a charge no more
        than the cost of distribution to the recipient; and

    (b) You may distribute such Executable Form under the terms of this
        License, or sublicense it under different terms, provided that the
        license for the Executable Form does not attempt to limit or alter
        the recipients' rights in the Source Code Form under this License.

    3.3. Distribution of a Larger Work

    You may create and distribute a Larger Work under terms of Your choice,
    provided that You also comply with the requirements of this License for
    the Covered Software. If the Larger Work is a combination of Covered
    Software with a work governed by one or more Secondary Licenses, and the
    Covered Software is not Incompatible With Secondary Licenses, this
    License permits You to additionally distribute such Covered Software
    under the terms of such Secondary License(s), so that the recipient of
    the Larger Work may, at their option, further distribute the Covered
    Software under the terms of either this License or such Secondary
    License(s).

    3.4. Notices

    You may not remove or alter the substance of any license notices
    (including copyright notices, patent notices, disclaimers of warranty,
    or limitations of liability) contained within the Source Code Form of
    the Covered Software, except that You may alter any license notices to
    the extent required to remedy known factual inaccuracies.

    3.5. Application of Additional Terms

    You may choose to offer, and to charge a fee for, warranty, support,
    indemnity or liability obligations to one or more recipients of Covered
    Software. However, You may do so only on Your own behalf, and not on
    behalf of any Contributor. You must make it absolutely clear that any
    such warranty, support, indemnity, or liability obligation is offered by
    You alone, and You hereby agree to indemnify every Contributor for any
    liability incurred by such Contributor as a result of warranty, support,
    indemnity or liability terms You offer. You may include additional
    disclaimers of warranty and limitations of liability specific to any
    jurisdiction.

    4. Inability to Comply Due to Statute or Regulation
    ---------------------------------------------------

    If it is impossible for You to comply with any of the terms of this
    License with respect to some or all of the Covered Software due to
    statute, judicial order, or regulation then You must: (a) comply with
    the terms of this License to the maximum extent possible; and (b)
    describe the limitations and the code they affect. Such description must
    be placed in a text file included with all distributions of the Covered
    Software under this License. Except to the extent prohibited by statute
    or regulation, such description must be sufficiently detailed for a
    recipient of ordinary skill to be able to understand it.

    5. Termination
    --------------

    5.1. The rights granted under this License will terminate automatically
    if You fail to comply with any of its terms. However, if You become
    compliant, then the rights granted under this License from a particular
    Contributor are reinstated (a) provisionally, unless and until such
    Contributor explicitly and finally terminates Your grants, and (b) on an
    ongoing basis, if such Contributor fails to notify You of the
    non-compliance by some reasonable means prior to 60 days after You have
    come back into compliance. Moreover, Your grants from a particular
    Contributor are reinstated on an ongoing basis if such Contributor
    notifies You of the non-compliance by some reasonable means, this is the
    first time You have received notice of non-compliance with this License
    from such Contributor, and You become compliant prior to 30 days after
    Your receipt of the notice.

    5.2. If You initiate litigation against any entity by asserting a patent
    infringement claim (excluding declaratory judgment actions,
    counter-claims, and cross-claims) alleging that a Contributor Version
    directly or indirectly infringes any patent, then the rights granted to
    You by any and all Contributors for the Covered Software under Section
    2.1 of this License shall terminate.

    5.3. In the event of termination under Sections 5.1 or 5.2 above, all
    end user license agreements (excluding distributors and resellers) which
    have been validly granted by You or Your distributors under this License
    prior to termination shall survive termination.

    *  Under no circumstances and under no legal theory, whether tort      *
    *  (including negligence), contract, or otherwise, shall any           *
    *  Contributor, or anyone who distributes Covered Software as          *

    *  special, incidental, or consequential damages of any character      *
    *  including, without limitation, damages for lost profits, loss of    *
    *  goodwill, work stoppage, computer failure or malfunction, or any    *
    *  and all other commercial damages or losses, even if such party      *
    *  shall have been informed of the possibility of such damages. This   *
    *  limitation of liability shall not apply to liability for death or   *
    *  personal injury resulting from such party's negligence to the       *
    *  extent applicable law prohibits such limitation. Some               *
    *  jurisdictions do not allow the exclusion or limitation of           *
    *  incidental or consequential damages, so this exclusion and          *
