RAD Editor converts relative https links to absolute

Valid for Sitecore 5.3

Problem: When using the Sitecore back-end with the https protocol there is a problem with the RAD Editor which converts relative links to absolute links with a https prefix in Rich Text fields. There is the same problem with links to anchors.

Workaround: This problem can be fixed by writing an additional processor for the saveUI pipeline. The code replaces all the following entries <a href=”https://DOMAIN with <a href=” if the current domain is equal to the domain of the link in the Rich Text fields.

using System.Text.RegularExpressions;

using Sitecore;

using Sitecore.Data.Fields;

using Sitecore.Data.Items;

using Sitecore.Pipelines.Save;

using Sitecore.Web;

namespace custom.https

{

public class FixHttps

{

private readonly string startPattern;

private readonly string replacement;

public FixHttps()

{

startPattern = string.Format("<a href=\"https://{0}", WebUtil.GetHostName());

replacement = "<a href=\"";

}

public void Process(SaveArgs args)

{

foreach (SaveArgs.SaveItem item in args.Items)

{

Item itemContext = Context.ContentDatabase.Items[item.ID, item.Language, item.Version];

if (itemContext != null)

{

foreach (SaveArgs.SaveField field in item.Fields)

{

Field fieldCurrent = itemContext.Fields[field.ID];

if ((fieldCurrent.Type == "html") || (fieldCurrent.Type == "rich text"))

{

field.Value = TightenHTTPSRelativeItemLinks(field.Value);

}

private string TightenHTTPSRelativeItemLinks(string html)

{

if (html != string.Empty)

{

html = Regex.Replace(html, "<a([^>]*)>", HttpsEvaluator, RegexOptions.Singleline | RegexOptions.IgnoreCase);

}

return html;

}

private string HttpsEvaluator(Match match)

{

string input = match.Value;

if (input.ToLower().StartsWith(startPattern))

{

input = input.ToLower().Replace(startPattern, replacement);

return input;

}

return match.Value;

}

Note: Please remember to insert the processor in the right place:

<processor mode="on" type="custom.https.FixHttps, custom.dll " />
